What You're Up Against

Level 731 paints Rainbow with 388 tiles across 5 colors, split into 12 cubes in the tray. You have 5 waiting slots and two nest holes.

  • Green: 102 tiles → cubes of 48, 40, 14
  • Cream: 86 tiles → cubes of 34, 26, 26
  • Jade: 74 tiles → cubes of 54, 20
  • Cyan: 66 tiles → cubes of 40, 26
  • Navy: 60 tiles → cubes of 32, 28

⚠️ 2 hidden “?” cubes in the tray.

Spoiler: what they hide

Navy 28, Navy 32

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 26 cube.
  2. Send the Green 14 cube.
  3. Send the Cyan 40 cube. Only ~26 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.
  4. Send the Jade 20 cube.
  5. Send the Jade 54 cube. Only ~30 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.
  6. Send the Green 40 cube.
  7. Send the Green 48 cube. Only ~26 of its 48 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 Cream 34 cube.
  9. Send the Cream 26 cube.
  10. Send the Cream 26 cube. Only ~24 of its 26 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
  11. Send the Navy 32 cube.
  12. Send the Navy 28 cube. Only ~27 of its 28 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.
