Sands of Eternity is a 729-way slot that can expand to a maximum of 46,656 ways, boasting an RTP of 96.16%. This Egyptian-themed slot comes with an intriguing "avalanche" payout mechanic and unique features that set it apart from the rest of Slotmill's offerings. Let's dive deeper into this slot to see if it's another winner from the developer.

Sands of Eternity takes a classic Egyptian theme and infuses it with Slotmill's unique twist. The symbols may not be as intricately designed as in some of their previous games, but personal preferences play a role in this assessment. The ambient background music blends well with the theme, creating an immersive experience.

Considering the massive number of pay ways (up to 46,656), it's not surprising that individual symbol payouts are lower than in some other slots. For instance, the top symbol, a purple mask, pays just 3x your stake for a full six-of-a-kind combination. However, remember that the game's stacked symbols and avalanche mechanic can lead to multiple simultaneous wins, potentially resulting in significant payouts.

Betting in Sands of Eternity accommodates a wide range of players, with a minimum bet of €0.20 and a maximum of €40. These limits should cater to most online slot enthusiasts.

Sands of Eternity immediately stands out with its unique grid structure. The initial layout features six spaces wide by three spaces tall, but as you win, blocks are removed from the outer edges, gradually expanding the pay ways from 729 to a whopping 46,656.

The game introduces special stone block modifiers that enhance the gameplay:

Wild Scarab: Found in the upper-left corner, this stone block transforms into wild symbols.

Eye of Horus: Located in the upper-right corner, this stone block converts low-paying symbols into high-paying ones when it explodes.

Golden Scarab: Hiding in the bottom-right corner, these blocks trigger a special mode where a 2x2 wild symbol is added to the reels in a random location.

Additionally, a Random Expansion feature can trigger during the base game, expanding the potential win ways to 20,736.

For those seeking a different experience, there's the Burst Mode Feature. This option allows you to select a bet size and the number of spins, and the game automatically accumulates your winnings, challenging you to exceed your total bet.

The bonus round in Sands of Eternity is triggered by landing three or more bonus symbols during the base game. Bonus symbols explode adjacent stone blocks, making it easier to hit the required count. The number of free spins you receive depends on how many bonus symbols trigger the feature:

3 Bonus Symbols: 9 Free Spins

4 Bonus Symbols: 12 Free Spins

5 Bonus Symbols: 15 Free Spins

6 Bonus Symbols: 18 Free Spins

During the bonus round, regular stone blocks on the reels can contain multipliers or additional free spins, potentially leading to substantial rewards.
