Tower of Ra Slot Review — RTP, Features & Where to Play

Tower of Ra

Crazy Tooth Studio · 2025

A 5×3 Ancient Egyptian slot from Crazy Tooth Studio. The Ra Multiplier Feature charges via Big BuildUp symbols — when Ra's staff fills, a random trigger distributes multipliers across the reels. The Tower of Ra Bonus is triggered by 3–5 Scatters: expanding single-space reels expand the prize structure tier by tier, with Advance symbols progressing play and Skull symbols disabling individual reels. Wild Multipliers of 2×–10× appear in the base game. Max win: 9,776×.

About the game

Tower of Ra is Crazy Tooth Studio's September 2025 Ancient Egyptian slot, distributed through Games Global. The 5×3 grid with 21 fixed paylines features Ra, golden relics, scarabs and the sacred tower against a desert temple backdrop.

Wild Multipliers appear throughout the base game at values of 2×, 3×, 5×, 7× or 10× — any win involving a multiplier Wild applies that multiplier to the total prize. The Ra Multiplier Feature is the base game charge mechanic. Big BuildUp symbols accumulate charge in Ra's staff meter. When the meter fills, a random trigger event fires — distributing multiplier values across active reel positions for the current and subsequent spins.

The Tower of Ra Bonus is the primary bonus event, triggered by 3 to 5 Scatter symbols anywhere on the reels. Inside the bonus, individual reel spaces expand progressively through the prize structure — Advance symbols move the active position up the tower toward higher prize tiers, while Skull symbols disable individual reels (removing them from the bonus progression). The escalating structure pushes theoretical values toward the 9,776× maximum win.
