How the Game Plays

Valley of the Dead OnlyWins BoltLock transports the series from Egyptian sands to the Greek underworld of Hades and Persephone. The game begins on a diamond-shaped grid with a 1-3-5-3-1 configuration, providing 45 ways to win. Winning combinations are formed by landing three or more matching symbols on adjacent reels starting from the leftmost position. As wins occur, the grid progressively expands, eventually reaching a full 5x5 layout with 3,125 ways to win.

BoltLock & Respins Explained

Every winning spin triggers an automatic respin. During these respins, winning symbols release "souls" that destroy the 12 BoltLock blockers (skull icons) surrounding the active reels. As these blockers vanish, more symbol positions are unlocked. If you manage to clear all 12 blockers in a single sequence of respins, you activate the Multiplier and Extra Lives features. Multipliers increase by 1x for every five blue souls collected from winning symbols, while every five red souls collected grant an Extra Life, which provides a free respin even on a non-winning turn.

OnlyWins GEM Explained

This title introduces the OnlyWins mechanic, a unique engagement feature that allows for guaranteed winning spins. By choosing to activate this mode, you pay a premium (4.4x the base bet) to ensure the next spin results in a win, which significantly accelerates the process of destroying blockers and reaching the bonus features. A "Multi OnlyWins" option is also available, allowing for ten consecutive guaranteed winning spins.
