Apex Protocol Features & Bonus Games

This slot machine game features everything from free spins and expanding Wilds to bonus games and Sticky Wilds.

Sticky Wilds

You will encounter sticky wilds during the Bonus Mode and Super Bonus features. This enables wilds to remain on the reels, which later become expanding wilds.

Expanding Wild

The golden “W” is the Wild, and landing 4 wild symbols with the combined multiplier on a reel will initiate the Expanding Wild protocol. These are especially exciting during the Bonus Mode and Super Bonus feature.

Bonus Mode

Landing 3 bonus symbols, which act as scatter symbols, in the base game triggers the Bonus Mode, which produces 10 free spins. During this mode, you have an increased chance of landing Wilds.

Super Bonus

This bonus game produces 10 free spins, but you need 4 or more bonus symbols to trigger this feature. You start the round with one expanded reel. The chances of Wilds landing are also increased during the feature.

Bonus Feature Spins Option

In this online slot, you have more than one Bonus Feature Spin option:

Bonus Booster - Uses 3x per spin
Bonus Mode - Uses 100x per spin
Super Bonus - Uses 250x per spin

Max Win & Return to Player (RTP)

Every spin is controlled by a random number generator (RNG) to ensure a random and provably fair - even during the game’s bonus rounds.

With a high volatility and 96.00% theoretical return-to-player percentage (RTP), you can aim for a 10,000x max win.
