Big Bass Bonanza Hold & Spinner can be played for anywhere from 0.10 to 250 per spin, regardless of platform. The game's default RTP of 96.07% is based on regular wagering in this mode.
There are 10 fixed paylines available on the game board, which consists of 5 reels and 3 rows. Line wins in this fishing game aren't as valuable as collecting Fish Money symbols or striking Money symbols, but they still help. For instance, winning 20 to 200 times your wager for a line of five identical Fish Money symbols, tackle boxes, dragonflies, reels or floats is possible. Not fantastic, but not terrible either: a payout of 5 to 10 times the initial wager for a hand of 10 A cards. In addition, wilds can act as substitutes for regular pay symbols during bonus rounds.
Free spins of 10, 15, or 20 games are triggered, accordingly, when 3–5 Scatters appear during the main game. Whenever a wild symbol appears during free games, it adds up the values of all Fish Money symbols in view. Fish Money icons can be worth anything from two times to ten thousand times the wager. In addition, the metre above the reels will add up each landing wild. The multiplier for Fish Money symbols increases by a factor of x2 after collecting the first four wilds, to x3 after collecting the next four, and to x10 after collecting the final four wilds. When this happens, you get an extra ten spins absolutely free. The retriggered free spins begin at the current multiplier level after the current round of free spins concludes. Once the maximum of three times has been reached, the free spins cannot be retriggered.
If a wild symbol appears on the grid but no Fish Money symbols do, then the bazooka will randomly add some Fish Money symbols to the grid.
When coins or diamonds representing currency appear, their values range from 1x to 2,000x the wager. The Hold & Spinner bonus round begins when three Money symbols appear. If nothing but blank spaces or Money symbols land on a reel, you get 4 free spins. After the Money symbols that triggered the round have paid out, they will stay put until the round is over. When more Money symbols land, the respin counter is reset and the values of the newly landed symbols are added to the values of the stuck Money symbols. The signs for the new currency don't stick.
