Play Big BuildUp Tower of RA Megaclimb Bonus with Bonuses at Spin Genie in the UK

Released by Relax Gaming in 2023, this activity takes players up a towering pyramid structure inspired by the god Ra. Unlike standard five-reel formats, this title uses a rising tower grid where each win pushes the action higher. The Megaclimb feature is the core engine here — it rewards consistent wins with multiplier boosts at each new level. The game sits at medium-to-high variance with an RTP of 96.12% and a max win potential of 10,000×. Spin Genie Casino is one of the places where fans can find this title ready to play.

How the Tower Mechanic Works

The Megaclimb system is what separates this title from other Egyptian-themed slots on the market. Each winning spin activates a climb — the tower rises one level and a multiplier is applied to the next payout. At higher levels, the multiplier can reach ×15 before the bonus round is even triggered.

Megaclimb Bonus Levels

The tower has 12 floors in total. Each floor brings a new multiplier value:

1. Floor 1–3 — ×1 to ×2 multiplier
2. Floor 4–6 — ×3 to ×5 multiplier
3. Floor 7–9 — ×6 to ×10 multiplier
4. Floor 10–12 — ×11 to ×15 multiplier, plus Free Spins trigger

Reaching Floor 12 unlocks the Ra Free Spins Bonus, where 10 to 20 spins are awarded with all active multipliers kept in place.

What Makes This Slot Different

Most Egyptian-themed titles follow the same formula — grid, wilds, free spins and done. This game at Spin Genie breaks that pattern with its vertical progression system. The tower does not reset after every non-winning spin. Instead, it holds its position for three consecutive non-wins before dropping one level. This gives gamblers a real sense of building toward something, rather than starting fresh each time.
