RTP (Return to Player) — the percentage of wagered money a slot is mathematically designed to return over millions of spins. Big Bass Splash's default is 96.71%, meaning the house keeps 3.29% long-term.
Volatility — a measure of risk. High volatility (Big Bass Splash is 5/5) means wins are less frequent but larger when they hit. Expect long dry stretches punctuated by bigger payouts.
Scatter — the green fish symbol that triggers free spins. Unlike regular symbols, scatters can appear anywhere on the reels — they don't need to be on a payline.
Wild — the fisherman symbol. Substitutes for all regular symbols and, during free spins, collects the cash value of any money fish on screen.
Multiplier — a value applied to winnings. In Big Bass Splash, the multiplier increases through 4 levels (1×, 2×, 3×, 10×) as you collect fisherman wilds during free spins.
Free Spins — a bonus round triggered by landing 3+ scatters. You spin without paying, and winnings are added to your balance. Big Bass Splash awards 10, 15, or 20 depending on scatter count.
Bonus Buy — a feature that lets you purchase instant entry to the free spins round for 100× your stake. Skips the base game but doesn't change the RTP.
Hit Rate — the percentage of spins that produce any win. Big Bass Splash's 13.66% means roughly 1 in 7 spins returns something, though most returns are small.
Paylines — fixed lines across the grid where matching symbols must land to form a win. Big Bass Splash has 10 fixed paylines running left to right.
Grid — the reel layout. Big Bass Splash uses a 5×3 grid (5 reels, 3 rows), the most common setup in online slots.
Money Symbols — fish symbols that carry random cash values (2× to 5,000× your bet). These values are collected by the fisherman wild during free spins.
Max Win — the highest possible payout from a single round. Big Bass Splash caps at 5,000× your stake. If reached mid-round, the feature ends immediately.
Modifiers — random enhancements selected before the free spins round begins. Big Bass Splash offers 5 possible modifiers that change the bonus round's behaviour.
Autoplay — a function that spins automatically for a set number of rounds. Not available in UKGC-regulated casinos.
