The Clockmaker throws Cogwheels onto the game board (a Cogwheel will glow one move before he throws it) ⚙️
You need to reduce his health bar to zero by matching special gems that deal damage to him ❤️🔥
💡 Tip:
Cogwheels can replace and destroy any boosters you may have on the game board, so be sure to use them before the Clockmaker's move.
