AvatarUX releases Sphinx Treasure on December 12th, 2025, a decent RTP (96.02%) Egyptian-themed slot with an exciting bonus feature. I particularly like the expanding reels, so you can land even more wins. In total, there are over 46,000 paylines, much more than the average video slot.

Full Rules & Information About the Sphinx Treasure Online Slot

Sphinx Treasure is a standard new US video slot set on a 6×3 reel. To begin the game, click the arrow button to the right of the screen. You can also edit your bet size or pick turbo or autospin mode for easier play.

Players can also press the express button to purchase the bonus spin rounds or up ante bets. The amount will depend on your coin size, and once purchased, the base game will transform into a bonus feature.

In the Sphinx Treasure slot, there are up to 46,656 ways to win, with the Sphinx feature capable of multiplying wins at random. The other key feature is that the 6×3 game can expand to 6×5. To do this, land a cascading winning combo, which will unlock the cell blockers (and get any rewards that go with it).

Sphinx Treasure Symbols & Payouts

The Sphinx Treasure symbols are Egyptian-themed. However, the lowest paying symbols are playing cards (9 – Ace). The ancient Egyptian symbols are the famous gods: Horus, Ra, Anubis, and Bastet. Landing 6 or more of these gods across the reels will bag you 2x your bet.

• All symbols: 11
• Highest-Paying Symbol: Egyptian Gods
• Wilds: Sticky Wilds
• Paylines Pay: Left to Right
• Maximum Win: 10,000x

Sphinx Treasure Bonuses & Features

The scatter symbol is the scarab (Bonus), where you’ll need to land three or more to trigger the free spins bonus round. Once triggered, the grid will expand to 6×6, giving you more ways to win. The Sphinx feature also allows for multipliers and unlocks new blocked cells.

I do enjoy the slow buildup of Sphinx Treasure, but you absolutely need patience and always keep your bankroll in mind. The volatility is high, so landing solid wins isn’t frequent.

Similar Games & Best Alternatives

As Sphinx Treasure is an Egypt-themed online slot, if you are looking for anything remotely similar, then hundreds are on offer. Nevertheless, in our opinion, nothing beats the most famous ancient Egypt slots such as Book of Dead or Cleopatra.

Pyramids, Paydays, and Patience

In Sphinx Treasure, I liked slowly unlocking extra rows, hitting the Sphinx feature, and watching multipliers pile up. However, the low 6-of-a-kind symbol pay means a lot rides on that bonus, so I’d treat it as an occasional high-risk thrill.
