Theme & Atmosphere 🖼️🎶
Setting: A floating rock island drifting through a pastel dawn sky. Each face of the crystal tower glitters with coloured cubes that shimmer like sci‑fi gemstones.
Visuals: Clean, neon‑tinted 3‑D blocks spin around a central axis, giving you that “hologram puzzle” vibe. When clusters hit, cubes burst into prismatic shards—chef’s kiss.
Soundtrack: An ethereal synth‑wave score builds subtle tension, punctuated by satisfying “click‑clack” tumbles as symbols cascade down the tower.
Tech Specs:
Grid: 5 reels × 5 rows per face (base game)
Pay System: Cluster Pays (wrap‑around)
Reactions: Winning cubes vanish, new blocks drop—a perpetual avalanche until no cluster remains.
Symbol Count: 80 in the base game, up to 160 in maxed‑out free spins!
It’s half Rubik’s Cube, half Jenga, and 100 % hypnotic. 😍

Bonus Features & Special Rounds 🎁
Free Spins in Depth
The feature begins with a 6‑row tower (96 symbols). On spins 3, 5, 7 and 9, one extra row is bolted underneath, eventually maxing out at 10 rows (160 symbols). Starting from the second free spin:
Only the bottom one or two rows disappear before each new spin, so most of the tower stays put, letting wilds accumulate.
Up to 10 random wilds drop into fresh positions at the start of every spin, dramatically boosting cluster potential.
Trigger Wilds remain active—each one inside a win adds +10 extra spins, potentially stretching your bonus round into double (or triple!) digits.
Maximising the Feature
Cluster Management – Premium cubes love hugging multiplier wilds. More surface area = more chances.
Retrigger Power – Every +10 spins keeps the tower tall and the wild storm rolling.
Bonus Buy Etiquette – Only pay 60× when bankroll can survive 100–150 spins without a big hit; otherwise, wait for organic triggers.
