Read full descriptionHide full description
Bus Loop is a smart puzzle game about timing, color, and order. Send buses from side lanes onto the main loop, pick up matching passengers, and clear the road without breaking the capacity limit. Gameplay Send buses: Tap to launch them onto the loop. Color match: Passengers board only their own color. Mind the limit: The loop has limited capacity—plan carefully. Clear the loop: When buses complete their run, the stage is solved. Features As you progress, new mechanics keep the puzzle fresh: Tunnels that connect unexpected road ends. Garages that release more buses than you thought. Covered buses whose colors stay hidden until revealed. Chains that unlock only when enough keys are collected. Gates that open and close, changing when passengers can board. Dual-colored buses that require more than one match to complete. Why Play Accessible controls, deep puzzles. Constantly evolving challenges. A satisfying flow as buses loop, fill, and exit. Perfect for quick play or long puzzle sessions. Think you can master the loop? Bus Loop will test every move.
