Lockstep vs Twin Drift

One move. Two boards. Think together. Lockstep is a daily logic puzzle where every move controls two boards at the same time. Swipe in a direction and both pieces move together — unless a wall, edge, or blocker holds one in place. Use that difference to reposition the boards and guide both pieces onto their matching goals at the same time. A new puzzle every day Each day brings a new Lockstep with a different challenge. Difficulty builds throughout the week, from lighter early-week puzzles to tougher Friday and Saturday boards. The Sunday Lockstep Sundays are different. The regular 4×4 boards expand to 5×5 for a larger weekly challenge built to test everything you’ve learned.
