Riddle Of The Sphinx

Riddle of the Sphinx is a 5-reel, 4-row slot from Red Tiger Gaming set amongst the sands of ancient Egypt. The game combines a straightforward 20-payline structure with a spreading wild mechanic: when a Sphinx symbol (the wild) lands, it expands to fill the reel, and adjacent reels can expand to match. This creates clusters of wild reels that generate significant multi-line payouts without triggering a bonus round—the base game itself becomes the focus.

The bonus feature offers players choice: select from multiple free spins packages with varying multiplier levels and spin counts. Higher multipliers come with fewer spins, whilst lower multipliers grant more. This flexibility allows players to tailor risk and reward to their preference. With a 94.72% RTP and high volatility, the slot leans towards risk-takers. Maximum win potential sits at 8002× your stake, achievable primarily during the bonus round where multiplier stacks can accumulate.

Visuals lean into classic Egyptian iconography—pharaoh masks, scarabs, the Eye of Ra—rendered in sharp detail. Stakes run from €0.20 to €100+ per spin, and the game is fully playable on mobile devices.
