## Description

Connect every node, sharpen every solve and climb an endless CHAIN IQ ladder through adaptive spatial puzzles.

Think fast. Connect smarter.

CHAIN is a focused spatial puzzle game built around one simple idea: connect the numbered nodes in order and complete the board with one clean chain. The rules are easy to understand, but every decision matters.

YOUR SKILL, ONE SCORE
Every first-time solve updates your CHAIN IQ, an in-game skill rating shaped by puzzle difficulty, speed, mistakes and hint use. Solve cleanly to climb from Iron through Grandmaster and Challenger, then continue into endless Apex tiers.

ENDLESS ADAPTIVE PUZZLES
After the opening levels, CHAIN generates fresh boards that adapt to your progress. Larger grids, more numbered nodes, obstacles and advanced mechanics appear as you improve—while occasional faster boards keep the rhythm satisfying.

BUILT FOR FOCUS
• Draw a single continuous chain
• Solve handcrafted and procedurally generated boards
• Face daily puzzles and build a streak
• Track precision, flawless solves and personal bests
• Use clear contextual hints when you need one
• Feel every connection through sound and haptic feedback
• Play on iPhone and iPad

NO ACCOUNT. NO ADS. NO TRACKING.
CHAIN is free to play. It requires no login, contains no advertising and does not collect personal data. Your progress stays on your device.

How high can you climb?
