Small tricks that crack hard Tumble Blocks levels

The later Tumble Blocks levels stop being about the perfect structure and start being about timing. Once I got that, a lot of them clicked.

A lot of solutions don't need to stand forever — they just need to hold for the one second the marble needs to pass. Building something deliberately unstable that collapses in the right direction is often the intended answer.

Use the rotate function more than you think. A block turned at an angle becomes a ramp, and a ramp solves half the game's problems.

And when you're truly stuck, restart and place your first block somewhere completely different. I wasted ages forcing the same wrong opening before I realised the puzzle wanted me to start from the other side.
