COPU: Color Puzzle Defense

Every match is a shot. Every second brings the serpent closer.

COPU: Color Puzzle Defense turns match-3 into a real-time defense battle. Swap neighboring tiles on a 7×7 board, create color matches, and fire volleys at matching serpent segments. Build chains, time special matches, and keep a tiny robot hero safe behind the wall.

300 LEVELS. 30 WORLDS. 29 MECHANICS.
Fight through a tactical campaign that keeps changing. Master armor, venom, waves, regeneration, Prism Relay, Rift Seals, Rune Chain, Core Overdrive, and more. Open the Field Manual whenever you need a refresher.

A FRESH TEST EVERY DAY
• Face a new Daily Challenge with a rotating mastery rule.
• Complete three daily goals and build your challenge streak.
• Push through endless Siege waves and chase a deeper record.

MASTER EVERY LEVEL
Return to cleared stages for Heroic objectives. Earn stars, Heroic medals, Mastery Seals, Ordeal marks, ranks, and cosmetic rewards, then track them in the Trophy Room.

OPTIONAL TACTICAL BOOSTS
Earn one-use boost charges through play. Optional in-app purchases offer COPUCOIN packs that can be spent on seven tactical boosts. Take up to two Tactics and one Gear boost into a run. Boosts are never required to complete the Campaign. Boosted Campaign wins still award stars and unlock progress, but do not set records or earn Heroic medals, Daily clears, or Siege best waves.

COPU is a single-player game with no ads. Core play and progress work locally. Link a Google account to protect and recover your cloud save. Color cues are reinforced with shapes, with controls for music, sound, haptics, and visual effects. The interface is available in 11 languages.

Defend the hero. Stop the serpent.
