Game Overview

Sanatorium Secrets is a medium volatility game where wins are multiplied by the base bet. All values are expressed as actual wins in coins. Only the highest win is paid per winning combination on the same payway, and winnings on multiple payways are added to the total win. Free Spins and Respin wins are added to the pay way win and are awarded after the round completes. The RTP is shown in-game; when using the ANTE BET, the RTP is shown in-game. The minimum bet is £0.20 and the maximum bet is £4.00. If there is a malfunction, all pays and plays are void.

Symbols

Wild Symbols

• 1×4 Wild Symbol: Can appear only on reels 2, 3, 4, and 5. Substitutes for all symbols except the SCATTER and SUPER SCATTER symbols. When it hits, it can randomly carry a multiplier of 4x or 8x, applied to all winning combinations it passes through. Multipliers add to each other if more than one is present in the same winning combination.
• 2×4 Wild Symbol: Can appear only on reels 3 and 4. Substitutes for all symbols except SCATTER and SUPER SCATTER. When it hits, it can randomly carry a multiplier of 8x, 16x, 32x, or 64x, applied to all winning combinations it passes through. Multipliers add together in the same combination.
• 1×1 Wild Symbol: Can appear only on reels 2, 3, 4, and 5. Substitutes for all symbols except SCATTER and SUPER SCATTER. This symbol appears only through the conversion of a high-paying symbol by the HOOK symbol.

Hook Symbol

• Can appear only on reels 1 and 6. When it hits, it grabs all high-paying symbols on the same row, transforming itself into a matching high-paying symbol or a cluster of them. It also converts high-paying symbols into 1×1 Wild symbols. If the HOOK passes over any WILD symbol, it doubles the Wild’s multiplier.

Scatter Symbols

• Scatter Symbol: Can appear on reels 2, 3, 4, or 5.
• Super Scatter Symbol: Can appear only on reel 6.

Free Spins

• Hit 3 or more SCATTER symbols to trigger the Free Spins feature.
• Hit 3 SCATTER symbols and 1 SUPER SCATTER symbol to trigger the Super Free Spins feature.

Puzzle Feature

• Before Free Spins, the PUZZLE feature is played. High-paying symbols can transform into Wild symbols when the associated reel is completed vertically with puzzle pieces.
• The PUZZLE feature starts with 3 respins. Each PUZZLE piece grants an extra respin and +1 free spin for the next round.
• During the PUZZLE feature, 1 or 2 HOOK symbols can randomly hit reels 1 or 6. These transform high-paying symbols and remain active throughout subsequent Free Spins rounds. If triggered with a SUPER SCATTER symbol, 2 HOOK symbols are guaranteed.
• A multiplier of +1x can appear on reel 1 or 6, increasing the minimum multiplier the 1×4 Wild symbols can have during the subsequent round.
• The feature ends when there are no respins left, or puzzle pieces fully cover reels 2, 3, 4, and 5, awarding the maximum potential win.

Free Spins and Super Free Spins Round

• Starts with 6 free spins plus 2 additional for each SCATTER beyond the third.
• For each puzzle piece hit in the PUZZLE feature, an extra free spin is awarded.
• New WILD symbols from the PUZZLE feature may appear on reels 2, 3, 4, and 5.
• When a HOOK symbol passes over a high-paying symbol transformed into WILD, it converts it to a 1×1 WILD and doubles its multiplier.
• Special reels are active during the feature.

Max Win

• The maximum potential win amount is limited to 10,000x the bet. If this limit is reached, the round ends immediately, and all remaining features are forfeited.

Ante Bet

• Players can choose the bet multiplier:
  • ANTE BET: Bet multiplier 40x. The chance to trigger Free Spins is four times higher.
  • Standard Play: Bet multiplier 20x.

Additional Rules

• Free Spins and Respin wins are credited to the player after the round completes.
• Free Spins and Respin win history includes the entire win of the cycle.
