Ice Lobster Slot from Pragmatic Play

Ice Lobster is a 5x3, 20-payline underwater fishing slot from Pragmatic Play. 96.06% RTP (note: some third-party sites list 96.53% — the PP info screen figure of 96.06% is the one used here), very high volatility (5/5), 5,000x maximum win. The mechanic is a Money Collect variant: red lobster symbols land with cash values of 0.5x to 1,000x the bet, and free spins create marked positions that accumulate those values when lobsters land there.

Free spins trigger on 3, 4, or 5 scatter anchors, awarding 8, 12, or 15 spins. During the bonus, the game tracks how many marked positions have been filled — at six filled positions a 2x multiplier activates; at ten filled positions the multiplier rises to 3x. That escalating multiplier on a fully-loaded board is the route to the 5,000x ceiling, though most bonus rounds resolve well below that without a sustained run of high-value lobster landings and multiplier activation.

The design wrinkle is the locked scatter positions: when scatters land during free spins they stay in position for the remainder of the round, narrowing the grid and concentrating subsequent lobster landings into fewer cells. This creates a compounding-value mechanic where a late-round board can have multiple high-value lobsters locked over previously marked positions. It is more strategic than most collect slots in terms of how position occupation matters.

The 96.06% RTP is the number to sit with. For context, Big Bass Bonanza — which runs a conceptually similar collect mechanic — offers 96.71% RTP with a 2,100x ceiling. Ice Lobster takes on more volatility, delivers a higher ceiling, and asks players to accept a steeper house edge in exchange. That trade-off is explicit; it is not a value-neutral swap.

Verdict
A collect slot with a compounding marked-position system and a 5,000x ceiling. The 96.06% RTP is the honest cost of that ceiling.
