Blocknado

Blocknado is a retro falling block puzzle with a twist, literally. There's a single rotating block in the middle of the board, and everything balances around it. The goal is to build complete rings. When a ring closes all the way around it collapses inward, pulling everything outside it in by one which can complete the next ring, and the next, potentially clearing the whole board. The main strategy is to set up all your rings such that you trigger a full chain reaction and clear the whole board. Points are awarded for each ring that is collapsed as well as a multiplier when more than one ring is collapsed at once. A total of 9 rings can be collapsed per cycle. The game speeds up after each cycle.

Here's the twist: to fill in the full ring you have to rotate the floor. To do this you have to slam your piece into the stack hard enough to give the whole structure momentum and turn it in the direction you want it to turn.
