A hex touches up to six neighbours, so a number can read 0 to 6. Every field is generated lazily: the first click is cleared and its neighbours re-counted, so you can never open on a charge. Clear all safe hexes to win; open a charge and the field is lost.

Watch the tiles light up, then repeat the sequence. Twelve levels.

Assign values to a circuit so every junction balances. One answer per network.

Slot satellites into orbits within a move budget. Each manifest has one solution.

Rotate pipe tiles around bedrock to connect source to sink.

Three batteries, six cities and a magazine that never refills. Twelve waves, four cities lost ends it.
