- 3) Drop the following Light Blue cluster into the Dark Blue Box that is waiting on lane 1, which takes the gray center countdown all the way to zero.

- 5) Poke the deeper Light Blue block revealed in Column 1 and drop it into the next Light Blue Box that rotates into the front row.
- 6) Keep the Yellow and Green clusters in Column 2 and Column 3 parked until a Box that matches them slides forward, then send them home.
- 7) Wipe the extra Dark Blue clusters buried at the bottom of Column 1 and Column 5, and funnel the top-heavy Green marbles down through the center lanes.
- 8) Toss the last Red and Yellow blocks that sit in the very top rows, wait for the animations to finish, then tap the closing matches to clear the board.
