What You're Up Against
Level 290 paints Donut with 208 tiles across 4 colors, split into 8 cubes in the tray. You have 5 waiting slots and two nest holes.
- Magenta: 88 tiles → cubes of 31, 29, 19, 9
- White: 86 tiles → cubes of 51, 35
- Yellow: 24 tiles → cubes of 24
- Blue: 10 tiles → cubes of 10
⚠️ 1 hidden “?” cube in the tray.
Spoiler: what they hide
Yellow 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 Magenta 31 cube.
- Send the Magenta 29 cube.
- Send the Magenta 9 cube.
- Send the White 51 cube. Only ~24 of its 51 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the White 35 cube. Only ~13 of its 35 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Magenta 19 cube.
- Send the Blue 10 cube.
- Send the Yellow 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.
