Game Rules

The game features a 1×4 WILD symbol. It can only appear on reels 2, 3, 4, and 5. It substitutes for all symbols except the SCATTER and SUPER SCATTER symbols. Each time it appears, it can randomly award a 4x or 8x multiplier. The multiplier is applied to all winning combinations that include it. If multiple multipliers are included in a winning combination, they are added together.

The slot also features a 2×4 WILD symbol. It appears only on reels 3 and 4. It substitutes for all symbols except the SCATTER and SUPER SCATTER symbols. Each time it appears, it can randomly award a multiplier of 8x, 16x, 32x, or 64x. The multiplier is applied to all winning combinations that include it. If multiple multipliers are included in a winning combination, they are summed up.

This is the HOOK symbol. It appears only on reels 1 and 6. Every time it lands, it captures all high-paying symbols on the same row, transforming into the corresponding high-paying symbol or cluster of them. It also turns these high-paying symbols into 1×1 WILD symbols. If the HOOK passes through any WILD symbol, it doubles that WILD’s multiplier.

The WILD symbol (1×1) can only appear on reels 2, 3, 4, and 5. Substitutes for all symbols except the SCATTER and SUPER SCATTER symbols. This symbol can only appear by transforming a high-paying symbol with the HOOK symbol.

This symbol is the SCATTER. It can appear on reels 2, 3, 4, and 5.

This is the SUPER SCATTER symbol. It can only appear on reel 6.

Free Spins

Land 3 or more SCATTER symbols to trigger the FREE SPINS feature. Landing 3 SCATTER symbols and 1 SUPER SCATTER symbol triggers the SUPER FREE SPINS feature. Before the round begins, the PUZZLE feature is played.

In the PUZZLE feature, high-paying symbols can turn into WILD symbols if the reel corresponding to the symbol above them is completely filled vertically with puzzle pieces. In the next round, they substitute for all symbols. During the next round, they can appear on reels 2, 3, 4, and 5.

The PUZZLE feature begins with 3 re-spins. Each time a PUZZLE piece lands on the screen, an additional re-spin + 1 free spin is awarded for the next round.

During the feature, 1 or 2 HOOK symbols can randomly appear on reels 1 or 6. Any HOOK symbol that lands will also appear in the next FREE SPINS feature throughout the round, appearing in a random position on each spin. If the round was triggered by a SUPER SCATTER symbol, 2 HOOK symbols are guaranteed to land in the PUZZLE feature, which will carry over to the next SUPER FREE SPINS feature.

In the PUZZLE feature, a +1x multiplier can appear on reels 1 or 6. Each multiplier increases the minimum multiplier that WILD symbols can land with 1×4 in the next round.

The round ends when there are no re-spins remaining or when the puzzle pieces completely cover reels 2, 3, 4 and 5. If the puzzle pieces completely cover reels 2, 3, 4 and 5, the maximum win is paid and the feature ends.

The FREE SPINS or SUPER FREE SPINS feature starts with 6 free spins plus an additional 2 for each Scatter beyond the third that triggered the feature.

For each puzzle piece landed in the previous PUZZLE feature, an additional free spin is awarded. During the feature, new WILD symbols, formed by transforming during the PUZZLE feature, may appear on reels 2, 3, 4, and 5.

Each time the HOOK symbol passes through a high-paying symbol that has transformed into a WILD, it transforms it back into a 1×1 WILD symbol and doubles its current multiplier. Special reels are included in the game.
