What You're Up Against

Level 901 paints Rainbow with 388 tiles across 5 colors, split into 14 cubes in the tray. You have 5 waiting slots and two nest holes.

  • Brown: 102 tiles → cubes of 54, 28, 20
  • Lime: 86 tiles → cubes of 36, 30, 20
  • Forest: 74 tiles → cubes of 51, 20, 3
  • Dark: 66 tiles → cubes of 33, 20, 13
  • Coral: 60 tiles → cubes of 39, 21

⚠️ 2 hidden “?” cubes in the tray.

Spoiler: what they hide

Coral 21, Coral 39

🔒 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 Dark 20 cube.
  2. Send the Brown 20 cube.
  3. Send the Dark 13 cube.
  4. Send the Forest 3 cube.
  5. Send the Dark 33 cube. Only ~24 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.
  6. Send the Forest 20 cube.
  7. Send the Forest 51 cube. Only ~30 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.
  8. Send the Brown 28 cube.
  9. Send the Brown 54 cube. Only ~32 of its 54 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
  10. Send the Lime 30 cube.
  11. Send the Lime 20 cube.
  12. Send the Lime 36 cube. Only ~29 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.
  13. Send the Coral 39 cube.
  14. Send the Coral 21 cube.

Finish without boosters for 3 stars and bonus coins. If the board jams anyway, a Shuffle or Vacuum booster is the cheapest way out.
