What You're Up Against
Level 620 paints Donut with 208 tiles across 4 colors, split into 9 cubes in the tray. You have 5 waiting slots and two nest holes.
- Pink: 88 tiles → cubes of 31, 29, 23, 5
- Forest: 86 tiles → cubes of 33, 32, 21
- Teal: 24 tiles → cubes of 24
- Black: 10 tiles → cubes of 10
⚠️ 1 hidden “?” cube in the tray.

Teal 24
Step-by-Step Solution
This loading order was computed from the web level layout with a reachability-first strategy: always feed the ants colors they can actually reach, and never let all 5 slots fill with blocked colors. Tap hidden “?” cubes only when you have slot room to absorb a surprise color.
Load the cubes in this order, letting the ants work between picks. Unless noted, a cube's tiles are fully reachable when you send it.
- Send the Pink 31 cube.
- Send the Pink 29 cube.
- Send the Forest 21 cube.
- Send the Pink 5 cube.
- Send the Forest 33 cube. Only ~20 of its 33 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Pink 23 cube. Only ~15 of its 23 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Forest 32 cube. Only ~18 of its 32 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Black 10 cube.
- Send the Teal 24 cube. Only ~12 of its 24 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
Finish without boosters for 3 stars and bonus coins. If the board jams anyway, a Shuffle or Vacuum booster is the cheapest way out.
