Place blocks on the grid to build your defense — enemies advance from the top. Clear each wave to earn a War Law (pick 1 of 3) that powers up the rest of your run. Connect 3+ blocks of the same color to activate formations. Tap How to Play on the main menu for the full rules and the enemy codex.
Real-time deals new block offers on a countdown timer. Phased lets you take your time — place your blocks, then tap Start Wave when ready. Switch anytime on the main menu or in Settings. Each mode has its own leaderboard.
Sign in to Game Center when prompted (or tap View Leaderboard after an endless run) and your endless scores and achievements sync automatically. Game Center is optional — the game works fully offline.
Progress is saved locally on your device: campaign stars, unlocks, enemy codex, and endless best scores. Note that uninstalling the app deletes local progress.
Try Phased mode for a relaxed, turn-based pace, or adjust Thinking Time in Settings (Standard / Relaxed / Casual) to slow down the real-time timer.
