Crystal Cove Tactics

Aim it. Bounce it. Clear the board.

A turn-based tactics game on a hex board of crystal tiles. Every tile hides a one-use projectile — pick it up, aim your throw, and bounce it off crystals to stack up power and effects before it lands.

  • 50-level campaign — a new map and winning strategy every level
  • Bounce physics — every crystal you ricochet off adds power and a stacking effect
  • Three hero races — Slime, Robot, and Fairy, each with its own projectile and powers
  • Boss duels, 1–6 rivals per level, and friendly fire for everyone

Puzzle · Panel Battle

Prism Cove Panic

Swap fast. Chain big. Bury your foe.

A fast crystal-panel battler played on a rising stack. Grab and drag panels to line up colours, set off chains and cascades, and send the stack crashing down on your opponent before yours tops out.

  • Enemy Fight — a 10-foe campaign, one new challenger per level
  • Puzzle mode — 100 hand-built boards with traps, tight move pars up to 8, and drop-insert solutions
  • One-cursor control — press to grab, drag to carry, built for mouse and touch alike
  • Big-cascade scoring — a few clever moves can detonate the whole stack
