Greentube introduces a new Sync ‘N’ Spin mechanic in its Egyptian Underworld slot release.

Greentube, Egyptian Underworld

The mechanic sees all winning symbols respin, a function which ends when no more winning combinations are present on the five reels.

Multiplier icons sit on top of the reels and meters are filled when wins with matching symbols occur. Once an icon is fully lit following two wins, players automatically receive 10 free spins, with the corresponding multiplier applied to all wins.

During the bonus, any golden eagle symbols that land on the reels grow a multiplier ladder, increasing the overall prize values. And each completed multiplier icon awards five further free spins.

Michael Bauer, CFO/CGO at Greentube, the Novomatic Digital Gaming and Entertainment Division, said the developer has become “synonymous” with Egyptian-themed games and backed the Sync ‘N’ Spin mechanic in Egyptian Underworld to “capture the imaginations” of players.
