Mystic Wreck is a five-reel, 5x3 slot from Casino Technology with 10 fixed paylines and an underwater treasure theme. The game uses wild symbols, including a diver wild that can substitute for most other symbols, alongside scatters that trigger the bonus feature. The published RTP for this version is 94.5%, with high volatility noted in the game data.
In the demo version, players can play for free and review the paytable, reel layout and win lines before moving on to play for real money. Free Games award 15 rounds with an initial x2 multiplier, and the multiplier can rise to x10 during the feature. Additional free spins may be retriggered, keeping the same lines and bet per line as the qualifying spin.
The rules also include a Double Up option for winning spins under 25x total bet, where a card guess can double the result, or lose it. A Last Card mini-game is also shown in the help screens, adding a further card-based feature to the slot's bonus structure.
