Aurum Codex by Red Tiger Gaming is a 5-reel, 20-payline slot with an alchemy and mystical library setting. The game uses a medium-high volatility model, an RTP of 94.7%, and a bet range from 0.1 to 20. Symbols include themed books, skulls, quills, keys, and card-style values, all presented in a gold and purple design.
The main feature is Alchemy Wilds. These Wild symbols land on the first and fifth reels and lock for the next spin; if they appear on the same row, the symbols between them can transform into Golden Wilds. Wilds also substitute for paying symbols, which is explained in the paytable alongside multiplier rules for Wild combinations.
Players can use the demo version to play for free and practice before playing for real money. Free Spins are triggered by three bonus symbols on the centre reels, with up to 20 spins available in the feature. During Free Spins, Alchemy Wilds stay locked for the whole round, keeping the bonus mechanics active across successive spins.
