Ace Ventura Pet Detective

5-Reels243 Ways to Win

The main objective of Ace Ventura Pet Detective online slot is to spin the reels and land matching symbols from left to right across the reels. The slot also offers some exciting Bonus Features, including Free Games.

Please note: the game does not feature traditional paylines. There are 243 ways to win by matching symbols on consecutive reels beginning on reel 1. You need to land at least three consecutive symbols on the reels to achieve a Line Win. Thus you will be paid for a Line Win if you have matching symbols anywhere on reel 1, 2 and reel 3 etc.

How to Play:

  • When the game loads an informational screen will appear; select Play when you are ready to start.
  • You must first choose the value of your coin for the bet. This will be multiplied by 40 to get the Total Bet, i.e. the amount deducted from your balance for each spin.
  • When you have selected your bets click on the Spin button to spin the reels and start the Ace Ventura slot game. If you wish, you can turn on Turbo Mode; this skips game animations and allows for more rapid play.
  • You can also spin the reels using the Auto Play function; this allows you to set a number of spins to be played through consecutively. Click on the Auto Spin button and choose from 10, 25, 50 or 99 spins. The spins will start playing automatically and not stop unless you click on the Stop Auto Spins button (which replaces the Spin button) or you are awarded a Bonus Feature.
  • When the reels have come to rest after a spin, any winning combination will be clearly highlighted on screen. The amount won will be displayed in the Win Field. Wins are paid according to the Paytable. For a Line Win, multiply the relevant figure in the Paytable by the coin value. Only the highest win is paid on each of the 243 pathways. Multiple wins can occur; these are added together and paid as a total win.

Info Pages:

Clicking on the Info button, located on the bottom left of the screen, will open up the game’s informational pages, including the Paytable. You can move through the different pages using the arrows on the bottom right of the screen. Click on Reels to return to the main game. The pages are as follows:

  • Paytable – shows the different payouts for all winning combinations.
  • The Ways – describes the special 243 payline structure of the game reels.
  • Free Games – describes the Free Games Bonus and how you can collect Modifiers in the main game.
  • In Reel Modifiers – explains the in-reel modifiers from that can be triggered in the main game.

Ways to Win:

As mentioned above there are no traditional paylines, or if you look at it another way, there are 243 different paylines. This means that every symbol works like an adjacent scatter, i.e. you will be paid for a Line Win if you land matching symbols anywhere on three or more consecutive reels (starting with reel 1).

Please note: there is a difference between the Line Bet and the Total Bet. The Line Bet is the same as the coin value, whereas the Total Bet is the coin value x 40. The latter is the amount deducted for each spin.

About Payouts:

All payouts are listed on the Paytable screen. To calculate the value of a win, multiply the relevant figure from the Paytable by the value of your coin.

Please read the terms and conditions to view information on maximum payout limits.

Wild Symbol:

The Wild Symbol can substitute for all other standard symbols to form winning combinations. The Wild Symbol does not substitute for Bonus Scatter Symbol and Animal Modifiers.

There is no separate payout for a group of Wild Symbols.

Scatter Symbol:

The Scatter Symbol – represented by the Bonus Icon – appears on reels 1, 3 and 5 only. It does not have any monetary value. Instead, if you land the three Scatter Symbols anywhere on reels 1, 3 and 5 you will be awarded the Free Games Bonus.

Note: the Scatter Symbol does not appear during Free Games, or during any of the in-game features.

Animal Modifiers:

During the main game you can collect Animal Modifiers to use later in the Free Games Bonus. These Animal Modifiers offer special enhancements that can make the Free Games Bonus more lucrative. The Animal Modifiers are displayed in a section on the top left of the screen. You can click on it to access more information. There are six Animal Modifiers in total, each of which has a unique enhancement for Free Games. The six Animal Modifiers are:

  • Shark
  • Elephant
  • Gorilla
  • Bat
  • Pigeon
  • Dolphin

More information is given on each enhancement in the Free Games section below.

Important information on Animal Modifiers:

  • Each Animal Modifier is saved at the coin value used when it was awarded. For example, if you are playing for a coin value of £0.01 and saved two Animal Modifiers, you would not be awarded the Animal Modifiers if you increased the coin value to £0.10 and subsequently won Free Games.
  • Animal Modifiers are saved even if you quit your session and exit the game. When you log in and play again they will be still available when you win Free Games.
  • The Animal Modifiers appear on Reel 5 only. Only one can be awarded in a single spin.
  • There are three slots for Animal Modifiers on the top of the screen. Two are initially filled, whereas the third one is locked. When you land an Animal Modifier (that is not in the collection) it will move the leftmost Animal Modifier out, fill the middle position, and move the Animal Modifier from the middle position one place to the left. The locked position will be unlocked and filled with an Animal Modifier if you land one with a special key symbol on Reel 5.
  • If an Animal Modifier appears on Reel 5 that is already in the collection above you will be awarded a cash amount.

Free Games:

If you land three Bonus Scatter Symbols on reels 1, 3 and 5 you will be awarded seven Free Games with the current Animal Modifiers. The number of Free Games may be increased, depending on which Animal Modifiers are in the collection. Below describes the six Animal Modifiers and the enhancements they offer for Free Games:

  • Shark – randomly increases the number of Free Games before they commence.
  • Elephant – adds an extra row to the reels, meaning there are 1,024 ways to win in Free Games.
  • Dolphin – randomly increases the Win Multiplier, applicable to all wins during Free Games.
  • Gorilla – chooses a random symbol and upgrades it to the highest paying symbol for each spin that it lands on the reels.
  • Bat – turns random positions on the reels wild for the duration of Free Games.
  • Pigeon – applies a multiplier to any win featuring a Wild Symbol on the middle reel.

Other information on Free Games:

  • Click Ok to start the Free Games Bonus, which will be played with the current Animal Modifiers in the collection.
  • Free Games will play through automatically.
  • The current amount won is displayed in the Free Spins Box.
  • Animal Modifiers and Bonus Scatters do not appear during Free Games.
  • When the Free Games Bonus has ended the total win will be displayed on a summary screen. Click Ok to return the main game.
  • After Free Games, the Animal Modifiers collection will be reset. If you had unlocked the third position, this will be unlocked once more. Two random Animal Modifiers will fill the first two positions.
  • Free Games are always played at the same coin value as the triggering spin. This cannot be adjusted.

In-Reel Features:

There are three in-reel bonus features that can be triggered randomly in the base game. These are as follows:

Jungle Friends:

  • Ace will appear randomly and summon his Jungle Friends to turn random positions on the reels wild.
  • The spin will play out as normal with the extra Wild Symbols

Sneaky Walk:

  • Ace will appear randomly stopping on one or more reels to turn that entire reel wild.
  • The spin will play out as normal with the extra Wild Reels.

Loser! :

  • After a non-winning spin Ace can appear and offer a free re-spin. A 2x multiplier is applied to this respin. If the repsin is again not successful the multiplier will again be increased (by between x1 and x3). This process will repeat until a winning spin occurs, with the winnings being subject to the multiplier.
  • The coin value cannot be adjusted during this feature.

Return to Player:

The theoretical RTP (Return to Player) for Ace Ventura slot at William Hill Casino is 96.178%. This is based on long term average and not a guarantee for a single session.

How to play casino games

Here's a rundown of some of our most popular online casino games, including how to play them, and which offers the highest payouts.

Online slots

Online slots are played more than any other online casino games. They’re relatively simple to play, which makes them a great option for beginners. Slots can also offer large payouts, particularly for a jackpot win.

Playing slots online is very straightforward. The simplest form of online slots are three-reel slots, which are based on the traditional fruit machines you may have seen in arcades. In these slots, you’ll see three columns and three rows of symbols, with the middle row being the payline. You place your bet and spin the reel, and if you get a winning combination, you win the amount stated on the paytable.

There are many other kinds of slots online available at William Hill Canada, such as five-reel slots and video slots, but they essentially work in the same way. While the odds of winning at slots are slimmer than other online casino games, they do allow you to play with small stakes on a wide variety of slots. Slots with a jackpot offer a larger prize pool, so let’s have a look at those next.

Jackpot slots

The main difference between regular online slots and jackpot slots is that the former have a lower maximum payout. With jackpot slots, however, there are larger top prizes, sometimes offering up to a seven-digit win on just a single spin.

While 'jackpot' can refer to a fixed huge cash prize awarded during jackpot games, the term is also used to describe progressive slot games. For fixed jackpot slots the size of the jackpot is, well, a fixed amount. With a progressive slot, the size of the jackpot increases each time a player places a bet on the game. Progressive jackpot slots are a great way to add to your online gambling experience. These games can offer some of the most exciting experiences of all casino games, as they provide you with the chance to win the biggest payouts you'll find online.

Online roulette

Online roulette games consist of a wheel with spaces that are either red or black and are numbered from 1-36. This popular game is easy to learn and even easier to play. All you need to do is predict where the ball will land and place your bet. The roulette wheel then spins, and if it lands on where you placed your bet, you win.

You may think that only one variant of roulette exists in online casinos, as this is typically the case at real-world casinos. However, at William Hill Canada, you’ll find multiple variants available, including a European version with one zero, and an American version with two. You’ll also find a French version that offers slightly improved odds if you bet on an even-money proposition.

Online blackjack

To win at online blackjack, you need a higher number than the dealer without exceeding 21. You are dealt two cards and can ask for another card as many times as you want before you reach 21.

One of the great things about playing online blackjack is the number of variants available. At a real-world casino, you’re restricted to just one or two games, but you'll find more here at William Hill Canada, including Blackjack Scratch, Royale Blackjack, and Blackjack Super 21.

Live casino games online

This is where online casino technology really comes into its own. Some players enjoy the thrills provided by a real-life casino but also enjoy the convenience of playing online. Live casino offers the ultimate experience to these players. The only difference between playing live casino at home and playing at a land-based casino is that with the former, the action is live-streamed to your device.

You’ll be playing at real tables, with real cards, and with real croupiers dealing your cards or spinning the wheel. Depending on the game, you'll also be playing with other players from all over the globe. With the ability to enjoy live chat with both players and the dealer, live casino offers a fantastic opportunity to enjoy an immersive experience while playing your favourite casino games online.

Enjoy free online casino games with casino bonuses

An online casino bonus is a great way to boost your balance with extra funds and make playing your favourite online slots even more fun. Casino bonuses come in a number of different forms and are applicable to a variety of online casino games.

Almost all casinos bonuses are subject to their own terms and conditions, but what you get back is certainly worth it. If you look at our current bonuses, you’ll see our welcome offer, along with any other offers we may have available. There isn’t a one-size-fits-all bonus, so just make sure to keep your eye on our bonus page in order to enjoy our selection of games the fullest.
