What You're Up Against

Level 1237 paints Moon with 484 tiles across 4 colors, split into 15 cubes in the tray. You have 5 waiting slots and two nest holes.

  • Navy: 355 tiles → cubes of 54, 52, 47, 45, 43, 39, 35, 23, 17
  • Coral: 104 tiles → cubes of 39, 33, 21, 11
  • Red: 13 tiles → cubes of 13
  • Indigo: 12 tiles → cubes of 12

⚠️ 2 hidden “?” cubes in the tray.

Spoiler: what they hide

Coral 11, Red 13

🔒 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 Navy 54 cube.
  2. Send the Navy 52 cube.
  3. Send the Navy 47 cube.
  4. Send the Navy 45 cube.
  5. Send the Navy 43 cube.
  6. Send the Navy 39 cube.
  7. Send the Navy 23 cube.
  8. Send the Coral 21 cube.
  9. Send the Navy 17 cube.
  10. Send the Coral 11 cube.
  11. Send the Coral 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.
  12. Send the Navy 35 cube. Only ~19 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.
  13. Send the Coral 39 cube. Only ~18 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.
  14. Send the Indigo 12 cube.
  15. Send the Red 13 cube. Only ~11 of its 13 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.
