The game is a hybrid slot, mixing a traditional three-reel slot with a second video screen above which features a game board. The reel symbols in the game include the traditional slot bars, 7’s alongside the game’s symbol and a Wild Mouse who takes up an entire reel. The game has nine paylines.

How the Mousetrap Slot Bonus Game Works

You’ll need 3 scatter symbols (which say ‘free games’) anywhere on the reels to trigger the bonus. First, you touch a mouse icon directly above the reels – which brings the board game to life.

You see a plastic mouse on the bottom left of the board. To start with, there are 7 free spins. What you are hoping for is symbols with small cheese wedges on them. These move the mouse around the board every time they appear. Any line hits during your free spins are counted up as usual.

On the board you will see spaces saying extra spin (sometimes two). There are cog shaped symbols on each corner with question marks on them.

These are what you want to hit – as they award jackpot prizes. You start at the mini jackpot and will either get this or an ‘advance’ after seeing an animation based on the Mousetrap board game. Advance gives you a shot at the next jackpot – right up to the biggest one.

If you keep hitting cheeses, you can win a lot more than just the initial 7 free spins.

On-Reel Features: Wilds and Doubles

Wild symbols show mice and are big enough to cover all 3 spots on a reel when they land flush. These appear on all the reels, giving you the chance of big wins over all 9 win-lines.

Trap Slot Items

What you want to see with winning combinations are the ‘double’ symbols. These are also wild, and as the name suggests will double any win they are part of. You’ll get a huge line prize by landing 3 of the double symbols on a win-line.

Cheeses will appear on the reels in the base game. These do not have any effect until you hit the free spins / board game bonus.

Mousetrap Slot Setup and Regular Wins

Mechanical reels mean you will sometimes hit ‘blanks’ instead of always having symbols in view. There are 9 win-lines in total, and your bets are in increments of 50c.

Other than the themed wild symbols, the winning combinations come from classic icons like 7’s and Bars. Red 7’s are worth hitting – especially if you are lucky enough to combine these with a double symbol. Bars come in the traditional 1, 2 and 3 variations.

• Based on the popular board game with mice, cheese and devious traps
• A penny slot with plenty of free games available and generous progressive jackpots
• Housed in WMS’s Blade Stepper offering a mechanical level and some traditional symbols

Mouse Trap slot is brought to you by WMS, a subsidiary of SG Gaming, based on the hugely popular mouse trap board game. The game itself involves players working together to build a mouse trap, designed by simple mechanical devices all joined together to form a more complicated trap, with players then turning against each other to attempt to capture their opponents’ mice. WMS have tried to incorporate some of the ideas from the board game into the slot, which is apparent from its design as well as some of the gameplay.

Mouse Trap slot is housed in the Blade Stepper, a modern design of the old school mechanical stepper, just like we saw with Aftershock Rumble slot. It features a traditional slot lever, and a mechanical stepper experience with gameplay kept relatively simple but up to date with the modern age of technology. The goal is to obtain a winning combination of base symbols, which are loosely based on the board game but with some traditional symbols involved also. These are listed here in ascending order based on their value:

• Any bar (lowest value)
• Bar
• Double Bar
• Tripler Bar
• Red 7’s
• Wild
• Double (highest value)

Wild will substitute for all of the above symbols excluding Double in a winning combination, while Double serves as a Wild symbol for all of the above symbols. Two Doubles also pay 4x any winning combination, except in Wild combinations. One Double pays 2x any winning combination, except when 2 Doubles show up.

If Wild symbols occupy line 1 at max bet, the the Top Progressive is awarded. If at less than max bet, 1250x total bet is awarded.

Mouse Trap Slot Bonuses and Features

Free Spins Bonus. This is triggered by 3 scattered Mouse Trap symbols in any position. 7 free spins are awarded, during which 3 additional scattered Mouse Trap symbols will award another 7 free spins. All line pays are doubled. At the start of the bonus, the mouse (at the top of the slot machine) starts at position 1 on the board. For each scattered cheese symbol, the mouse will move one position forward on the board. If he passes over a +1 or +2 symbol, then the corresponding number of free spins will be awarded and the +1 or +2 will double, but only on the first time the mouse passes that space. If at the end of a spin the mouse stops on one of the four corners of the board, then one of the four cheese prizes will be awarded randomly. If a cheese prize is awarded and the spin that triggered the bonus was at max bet, the cheese prize is replaced by the less than max bet cheese prize value for the remainder of the free spins. These cheese values are as follows:

At Less Than Max Bet:

• Minor – 5 credits
• Major – 15 credits
• Grand – 50 credits
• Cheddar – 250 credits

At Max Bet, the progressive jackpot is awarded.

The top progressive is awarded once during the free spins bonus, after which it is replaced by the less than max bet full reel value for the rest of the bonus. All pays are multiplied by the total bet, apart from the progressive. These are equivalent to the reset value plus any accrued increment since the last triggered progressive.

Conclusion

Mouse Trap Slot Game

Mouse Trap slot is an entertaining yet simple slot from WMS based on the popular board game of the same name. Housed in a modernized traditional slot, the game is easy to follow based mostly on one free spins bonus, which can certainly be very rewarding for a penny slot such as this. It’s fun too, although I think more could have been done to include more of the original board game’s features such as building contraptions. That being said, I think the theme is great will appeal to many.
