What You're Up Against

Level 400 paints Castle with 355 tiles across 6 colors, split into 13 cubes in the tray. You have 5 waiting slots and two nest holes.

  • Jade: 125 tiles → cubes of 43, 40, 23, 19
  • Cyan: 90 tiles → cubes of 39, 29, 22
  • Black: 54 tiles → cubes of 28, 22, 4
  • Aqua: 38 tiles → cubes of 38
  • Lime: 36 tiles → cubes of 36
  • Pink: 12 tiles → cubes of 12

⚠️ 2 hidden “?” cubes in the tray.

Spoiler: what they hide

Lime 36, Pink 12

🔒 1 locked cube — free the cube above them before they can be picked.

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.

  1. Send the Cyan 22 cube.
  2. Send the Black 4 cube.
  3. Send the Cyan 29 cube. Only ~21 of its 29 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
  4. Send the Lime 36 cube. Only ~21 of its 36 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
  5. Send the Cyan 39 cube. Only ~14 of its 39 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
  6. Send the Jade 19 cube.
  7. Send the Jade 23 cube. Only ~20 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.
  8. Send the Jade 43 cube. Only ~20 of its 43 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
  9. Send the Black 28 cube.
  10. Send the Black 22 cube.
  11. Send the Aqua 38 cube. Only ~22 of its 38 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
  12. Send the Jade 40 cube. Only ~22 of its 40 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
  13. Send the Pink 12 cube. Only ~10 of its 12 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.
