Cash Bonanza Slot by Pragmatic Play

Every spin starts at 6x4. That lasts about half a second. Any winning combination locks its symbols in place, then every other matching symbol on the grid locks too. Wilds and scatters stick. The reels with locked symbols grow taller by exactly the number of locked positions, and a respin fires. New matches lock again, reels stretch further, another respin. This keeps going until nothing new connects. At 6x8, you're looking at 262,144 ways - sixty-four times the starting count.

The grid resets after every completed spin in the base game. Free spins change that rule entirely. Eight spins to start (plus four for each extra scatter beyond three), and the grid carries over between spins at whatever size the triggering sequence reached. So if you enter free spins on a 6x7 grid, that's your new floor. Each respin during free spins also bumps a win multiplier by 1x - not cumulative across spins, just within each respin chain. But the grid growth is permanent for the round, which means later spins start with more ways already active.

Wilds during free spins roam and carry multipliers up to 5x. They move around the expanding grid between spins rather than staying fixed. Two or more scatters retrigger with four additional spins per scatter, no cap on retriggers. The whole bonus round builds momentum - wider grids feed bigger respin chains, which push the multiplier higher.

Visually it's classic fruit symbols - polished 3D cherries, watermelons, bells, red 7s - sitting inside a green metallic vault border with gold coins spilling from an open safe on the right side. The WAYS counter on the left updates live as reels expand, ticking from 4,096 up through 23,040 and beyond. No buy bonus option here.
