You can chose any coin denomination between 1 cent and 5 dollars and the max bet is equal to 20 coins. The top jackpot is 2,000 coins which you get in a case you hit five wild bell symbols on the payline. The next payout is 1,000 coins and you win it for two different combinations consisting either of five donuts or punch logos. The bell is the wild symbol which can substitute all the other symbols except of the dice, furthermore it acts as the multiplier and doubles the payouts.
The dice logo can appear only on the reels number 1, 3 and 5 and when they form such combination, the bonus feature is activated. The dice reveal some random number between 2 and 6, which means the multiplier number. You get 21 free spins with the current multiplier. In a case you re-trigger the feature you can get either 21 or 5 free spins.
Bunko Bonanza also provides the random progressive jackpot which starts from 1,000 coins.
