Tangle Tower Blocks

Tangle Tower Blocks is the game I keep on my phone for waiting rooms. You slide and rotate blocks to clear paths, and the difficulty ramps up gently until suddenly you're staring at a board for five minutes plotting three moves ahead. No internet needed at any point.

What I like is the lack of pressure — no clocks, no lives to run out. You solve at your own pace, and the undo button means you can experiment freely. The later levels get devious, with blocks that lock other blocks in place.

There's a soothing rhythm to it. It's not going to change your life, but as a clean, well-made puzzle box for offline moments, it does its job better than most.
