What You're Up Against

Level 51 paints Rainbow with 318 tiles across 5 colors, split into 14 cubes in the tray. You have 5 waiting slots and two nest holes.

  • Coral: 80 tiles → cubes of 28, 26, 20, 6
  • Yellow: 72 tiles → cubes of 31, 29, 12
  • Violet: 62 tiles → cubes of 39, 16, 7
  • Forest: 56 tiles → cubes of 29, 27
  • Blue: 48 tiles → cubes of 31, 17

⚠️ 2 hidden “?” cubes in the tray.

Spoiler: what they hide

Blue 31, Blue 17

🔒 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 Blue 17 cube.
  2. Send the Violet 7 cube.
  3. Send the Coral 6 cube.
  4. Send the Forest 27 cube. Only ~24 of its 27 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 Forest 29 cube. Only ~20 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.
  6. Send the Violet 16 cube.
  7. Send the Violet 39 cube. Only ~25 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.
  8. Send the Coral 28 cube.
  9. Send the Coral 26 cube.
  10. Send the Yellow 12 cube.
  11. Send the Yellow 29 cube. Only ~23 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.
  12. Send the Yellow 31 cube. Only ~26 of its 31 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 Blue 31 cube.
  14. Send the Coral 20 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.
