Step-by-step solution
- 1) Open by grabbing the Brown marble sitting in the middle of the bottom row and dropping it straight into the middle-left Brown Box, while you leave the Violet, Pink, and Green marbles on that same row alone.
- 2) Tap the free Red marble on the far right of the bottom row so it begins filling the front Red Box.
- 3) When a gap opens in column three, push the bait Purple marble onto the belt, then send the Yellow marble hovering above it into the middle-right Yellow Box.
- 4) Shift your focus to the far-left Black Box and pick through the freshly exposed marbles in columns three and five to feed it every Black marble you find.
- 5) Clear the surrounding center-grid marbles to trip the Lock and Key pegs; once both keys snap, the middle of the tray breaks open completely.
- 6) After the center gives way, use the Purple marble you stashed on the belt to clear the left-side Purple Box, which then reveals a Green Box underneath.
- 7) Drop the bright-green marble that rests at the base of column four into its box, then start pulling from the Tunnels but never trigger all five at the same moment.
- 8) Hold three free belt slots, empty the White Box early to free a Purple slot, and clear the bottom Boxes one column at a time to wrap up cleanly.
