ABOUT THE GAME

Canny the Can is back in Stack'em! This time he brought his friend Mona the Mouse with him.

Stack'em is a 5x6 grid game featuring a max win of up to 10,000x.

Stack symbols on top of each other to increase the multipliers shown below the reels. Keep stacking them to multiply your wins!

In the free spin mode all wins will increase the total multiplier with the size of the cluster. You enter the game mode with a fixed number of spins, shown as heart symbols above the reels.
The ? symbol will give a mystery reward which can be either additional spins or increase the multiplier.
If the X symbol connects with a win on the grid, the win will be multiplied by the factor shown above the reels

Multipliers

In the base game, non-winning symbols are removed after every win, and all winning symbols are kept and are dropped to the bottom of the grid. Below each reel, a value is shown indicating the number of winning stacked symbols in that reel. All winning clusters will be multiplied with the total of the multiplier values they are above. For example, if a winning cluster is above 1x, 3x and 2x, those multipliers will first be added together to a total of 6x, which will then be multiplied with the winning cluster amount. This process continues as long as you stack more wins.

Freespins

Get at least three free spin scatter symbols in the base game to trigger the free spin feature. You are initially awarded 5 free spins, displayed as hearts above the reels. The free spins mode continues until no more hearts remain. In free spins, all symbols are removed between each spin. Every time you hit a win in the free spins mode, the total multiplier will be increased by the number of winnings symbols.
Example: If a winning cluster consists of 6 symbols, 6 will be added to the total.

On each free spin there is a chance that the special X symbol appears. All winning clusters that connect with this symbol will be multiplied with the factor shown above the reels.

The ? symbol will give you additional spins or increase your multiplier. The following outcomes are possible:

- 2-5 additional lives
- Add one of the following to the total multiplier: 1, 2, 5, 10, 25 or 50
- Multiply the total multiplier by 2, 3, 4 or 5

SPIN

WIN

Winnings and winning combinations are paid according to the paytable. Multiple wins in one round are added together and the total round win will be displayed in the WIN field (to the right of BALANCE). Separate wins in a winning combination will be displayed during the win presentation. Symbol payouts are displayed in the paytable and reflect the current bet configuration. Only the highest win per winning way is paid. Some win amounts may be displayed in an abbreviated format using letters to represent large numbers. When a win amount is displayed in this format, the displayed value may be rounded down. The actual amount awarded will never be less than the displayed value.

MAX WIN

The maximum achievable win in this game is 10,000 times your bet. The maximum win may be achieved by triggering specific combinations and/or features. When this amount is reached the game will display a message indicating the maximum win has been reached. The current round will then immediately end and your winnings will be awarded. If this occurs during free spins and/or other bonus feature(s), the game will return to the main screen and any remaining free spins and/or other bonus feature(s) will be discarded.

MAX WIN

Maximum win: 10 000 times the total stake. Probability of getting the maximum win: 1:{baseGameMaxWinOdds}. The maximum win occurs when a cluster of Thumbs Up symbols lands on the grid and then, by subsequent drops, increases its size and is multiplied after each increase with the sum of multipliers shown below the reels.

In Free spins the total win for each spin is shown in the WIN field while the accumulating win for all free spins is shown in the TOTAL WIN field next to the number of remaining spins.

INTERRUPTED GAME

In the event of disconnection, a previously started round that has been interrupted may be resumed immediately by starting the game again. The results of a completed round (where display of the visual result was interrupted) will only be re-displayed within the game for winning rounds, but all game rounds may be reviewed in History. Any amount wagered on an unfinished game will remain paused until you either complete the game or the game is void as a result of account inactivity or system maintenance. When an unfinished game is void, your bet will be refunded to your account. Any awards earned on an unfinished round will not be credited unless you resume and complete the game. Winnings on unfinished game rounds where the player cannot further influence the outcome of the game will be automatically credited to the player's account after {payoutPeriod}. Game rounds that require additional player input to determine the outcome of the game will remain unfinished for {payoutPeriod}, after which a default choice will automatically be made in order to complete the round and credit any winnings to the player's account. Game rounds will never be affected by unforeseen external errors due to hardware, bandwidth, network errors or similar. Game rounds will be either stored and completed by the player at a later time or they will be closed and the wager will be refunded to the player. If an incomplete game round has not been resumed within {rollbackPeriod}, the round will be rolled back and the wager will be refunded.

HISTORY

The result of a completed game may be viewed in History. Results of unfinished games are not displayed in History.
