Mystery Museum shifts the scenery but keeps its gold stacks
Mystery Museum sits at an odd angle to this corner of the catalogue: its display cases hold Greek helmets and a samurai mask alongside the golden Pharaoh and the Eye of Horus. That is the documented frame, and it has consequences. Push Gaming's original Mystery-series build runs on 10 fixed lines with a High profile, and its Mystery Stack mechanic pays on any line position rather than demanding leftmost-reel continuity once three stacks turn gold. In Free Spins those stacks persist for the whole feature, revealing one shared symbol every spin. Egyptian readers get their iconography, but carried by a reveal system, not by stacked scarabs.
Game modes
Push Gaming's Mystery Museum runs on a 5x3 grid with ten fixed lines and a 96.58% base RTP, and each system below feeds the same loop: Mystery Stacks reveal one shared symbol across the reels, Wild Samurai scatters open 8 to 12 free spins, the Power Gamble trades risk for a 97.04% ceiling, and the Bonus Buy prices instant entry at 94.5x to 400x.
Base Game
Five reels of three, ten fixed lines: a line win counts only when matching symbols run consecutively from the leftmost reel, only the highest win per line is kept, and separate lines add together. Mystery Stacks can land here too; with three or more present they nudge to fill their reels, turn gold after ordinary line wins are paid, and reveal one shared symbol across all ten lines regardless of adjacency.
Mystery Stack
A full-reel stained-glass panel that occupies all three positions of its reel and is not itself a paying symbol. Below three on screen it stays blue and inert; once three or more are present, every stack turns gold and reveals the same paying symbol at once, paid on all ten lines even off the left-to-right rule, unless the ordinary line payout is higher.
Free Games Feature
Three, four or five Wild Samurai scatters anywhere award 8, 10 or 12 spins. Any Mystery Stack landing during the round stays for the remainder of the feature, and once three or more are present they turn gold and reveal a shared symbol every spin. The recorded purchase of the Random Scatters buy returned exactly three scatters and 8 spins.
Power Gamble (Gamble Up)
Any single win at or above the chosen threshold (2x to 50x bet, 5x by default) opens it automatically. Each step offers 1-in-4, 2-in-4 or 3-in-4 odds of climbing a cash meter, with a wrong pick losing progress. From 100x bet, that amount can be exchanged for the Free Games Feature. The documented best strategy, always 3-in-4 and always collect, raises RTP from 96.58% to 97.04%.
Bonus Buy
Four purchases guarantee an instant trigger, each priced off the base bet and rescaling with it: Three Scatters at 94.5x for 8 spins (96.21% RTP), Four Scatters at 212x for 10 spins (96.04%), Five Scatters at 400x for 12 spins (96.26%), and Random Scatters at 191.5x with a random count (96.32%). All four sit below the 96.58% base figure.
Launching the game and placing a bet
Mystery Museum is the Push Gaming title that named the Mystery series: a dim museum hall where relics of several ancient cultures share a 5-reel, 3-row grid and 10 Lines. A cycle here means staking, spinning and reading the reveal, with a Gamble decision whenever a win clears your threshold.

Read the outcome
Line wins count consecutively from the leftmost reel on the 10 Lines, only the highest per line. Three or more Mystery Stacks then turn gold and reveal one shared symbol paid on every line. A qualifying win opens the Power Gamble, while 3 or more Wild Samurai symbols anywhere trigger Free Spins.
