Game Payouts

Winnings paid out on the slot machine are dependent on the symbols displayed, once the reels have come to a stop.

All pay ways are permanently enabled for every spin, so you cannot select or de-select pay ways. All bet amounts are automatically multiplied by a 30 bet multiplier. So, if you bet 1 coin, you are betting 1 coin x 30 = 30 total coins bet per spin.

Regular Payouts

All payout figures show the number of coins that are won for each combination. The total number of coins paid out depends on the number of coins you play.

Regular wins are calculated by taking the number of coins won, multiplied by the number of coins bet. For each spin, the bet amount you choose is automatically multiplied by the bet multiplier.

The number of credits won is dependent on the total number of coins won multiplied by the coin size you select.

Multiple winning combinations are paid out per pay way. If there is more than one winning combination for different symbols on a pay way, you are paid out for each combination. If there is more than one winning combination for the same symbol on a pay way, you are paid out the value of the highest combination only.

If winning symbol combinations are displayed on multiple pay ways, you are paid out for each combination.

For a combination of regular symbols to produce a winning regular combination, the following criteria must be met:

• Three or more matching symbols must be displayed in any position on consecutive reels.
• Regular winning combinations pay out from left-to-right, so one symbol must be displayed on the first slot reel. A symbol combination starting from the second, third, fourth or fifth slot reel does not pay out.
• Scatter Symbol Payouts

Scatter wins are calculated by multiplying the scatter symbol combination payout by the total number of regular coins bet.

Scatter wins are added to regular wins. If you have a scatter win and a regular win, you are paid out for both wins, as the scatter symbol does not need to appear on consecutive reels to win.

For a combination of scatter symbols to produce a winning scatter combination, the following criteria must be met:

• Completes a winning scatter combination when two or more appear on the reels.
• Cannot be substituted by the wild symbol.
• Great Hall of Spins Bonus Game Payouts
