When to Use Convert
Convert changes a toy to a different type. Save it for situations where a single wrong toy is blocking a container from completing. Using it early wastes its potential.
Eliminate vs Refresh
Eliminate removes a toy entirely. Use it when a toy type has no available container. Refresh reshuffles the board. Try manual moves first before reshuffling, since the new layout might be worse.
Building Combos
Clearing multiple containers in quick succession without mistakes builds your combo multiplier. Higher combos earn more coins per level. Plan your moves to chain clears rather than solving one container at a time.
