Ice Trays 🧊
Obstacles & Locks

Ice Trays冰托盘

Clear nearby boxes twice to break the frozen tray!

How it works

  • An Ice Tray is a frozen bottom color box that needs two directly adjacent (left/right) colored boxes cleared to break the ice (diagonals do not count).
  • If the frozen tray is the only visible receiver for a color, dropping it too early leaves those marbles with nowhere to go.
  • Hard levels chain multiple Ice Trays together: break one ice to get a box, then use it to break the next.
Pro tip

Scan all frozen trays and prioritize the ones with the fewest neighbors. Hold blocked colors, and if one normal box touches two Ice Trays, clear it first — one clear paves the way for both. Break ice while the conveyor is calm.
