Hidden is a 5-reel ELK Studios slot with 178 ways to win and an Egyptian treasure-hunt theme. The reels use large falling blocks, so wins feel heavier than in standard online grid slots - Free slots online. Three magnifying glasses trigger Treasure Room Free Spins, starting with 5 spins. One visible symbol is picked as the expanding symbol and grows into 2×2 blocks during the bonus, while other symbols can clear away for another drop. The random Flashback Respins feature can appear in the base game, sending the reels back to ancient Egypt for three respins with one, two, or three sticky wild reels. Hidden slot has 96.3% RTP, 6/10 volatility, 24% hit frequency, and a max win of 215,000 coins, or 2,150x the bet.
