Why start with blue stacks?

They form the majority of the board and are the largest stacks; clearing them first opens the route for other colors.

What is the red stack for?

It is a smaller stack that should be cleared after the surrounding blue stacks to avoid blocking the route.

Clear the witch-on-cloud pixel art by routing the blue stacks first, managing the red and black stacks, and finishing with the white buffer cubes.

If the player asks you to sign in, open the video on YouTube instead.

Tap the largest blue stack (35) to start routing blue cubes to the matching blue hole.
Wait for several blue cubes to be carried before tapping other colors to free buffer space.
Clear the blue stacks systematically, moving from the bottom rows upward.
Route gray (30-40), yellow (30), and red (10-16) stacks as they become available.
Clear the black stacks (35) after the surrounding blue stacks are mostly empty.
Finish with the white buffer cubes and confirm the witch pixel art is fully cleared.

Board notes 5 details

Layout: A witch (magic girl) standing on a yellow cloud/platform, holding a magic wand, with blue sky and white cloud background. Bottom stacks include blue, gray, yellow, red, black, and white buffer slots. Initial stack counts: 40 (gray), 35 (black), 35 (blue), 38 (gray), 34 (white), and multiple 35 (blue) stacks.
Goal: Route all colored cubes into their matching holes to clear the board and reveal the witch-on-cloud pixel art. The witch figure is composed of purple robe, golden hair, and yellow cloud on a blue sky background. Pixel art counter starts at 1000.
Opening: Start with the largest blue stack (35) to open the blue route and prevent premature buffer filling.
Danger Zone: Tapping white buffers too early blocks the blue route. Clearing small stacks before the large blue stacks wastes buffer capacity. The red stack (10) appears later and must be cleared after surrounding blue stacks.
Mechanics: Multi-color board with a prominent witch-on-cloud pixel art. Blue stacks require coordinated routing, red and black stacks cleared after surrounding blue points, yellow cloud as final layer.
