Game Rules

This symbol is the Scatter. It appears on all reels.

These are MONEY symbols. On every spin, MONEY symbols are assigned a random cash value, which can be won if they are part of a winning combination or land within a frame. Possible values ​​are 0.5x, 1x, 1.5x, 2x, 2.5x, 3x, 4x, 5x, 7.5x, 8x, 10x, 15x, 20x (MINI), 40x (MINOR), 80x (MAJOR), 200x (GRAND), 400x, 800x, 2000x, or 10000x (MAXI) the base bet.

Frame Feature

During the base game, a 2×2, 3×3, 4×4, 5×5, or 6×6 frame may randomly appear at a random position on the screen.

Additionally, a second frame may randomly appear during the same spin. When two frames overlap and MONEY symbols land within the overlapping area, those MONEY symbols are assigned a random multiplier of 2x, 3x, 5x, 8x, or 10x, which multiplies the value displayed on the symbol. The values ​​of all MONEY symbols located within the frame are summed up and paid out.

Free Spins

Land 3, 4, 5, or 6 SCATTER symbols to trigger the FREE SPINS feature and win 6 free spins with 1, 2, 3, or 4 modifiers, respectively.

Before the round begins, eight coins appear on the screen. Click on them to reveal modifier names until you uncover a matching pair for each modifier awarded for the current round. Once a matching pair is revealed, that modifier will be applied to the upcoming round. Possible modifiers:

MORE – More CASH symbols appear on the reels during the next free spins round.

MORE – More SCATTER symbols appear on the reels during the next free spins round.

LEVEL UP – The round begins with the frame already expanded to 3×3.

DUAL – Two frames are guaranteed to appear on every free spin.

During the round, at least one frame is guaranteed to appear on every free spin.

Each Scatter symbol that lands during the round is collected on a meter above the reels. For every 3 collected Scatter symbols, the frame expands by one level—from 2×2 to 3×3, 4×4, 5×5, and up to a maximum of 6×6—and 2 additional free spins are awarded.

The frame expansion takes effect starting from the next free spin. If more than 3 Scatter symbols are collected during a single free spin, all corresponding upgrades are awarded. Special reels are used during play.
