BONK (automatic strike)
The hammer's hit. When a row reaches the strike line, the hammer BONKs the hole of its column by itself.
You never press a button to hit: you only move the hammer left and right between columns. Every time a row reaches the strike line at the bottom of the machine, the hammer strikes the hole of the column it is standing on. That hit is the direct BONK.
Every other hit on a hole is also a BONK. Hammer modules make extra hammer BONKs (Wide Head, Double Tap...), special moles and prizes make indirect BONKs (a Tesla arc, a Bomb blast...). All of them can pop moles and grow the chain.
The only question the game asks is: which column gives me the best next BONK?
