What You're Up Against

Level 309 paints Swan with 484 tiles across 5 colors, split into 17 cubes in the tray. You have 5 waiting slots and two nest holes.

  • Jade: 231 tiles → cubes of 54, 48, 40, 31, 27, 25, 6
  • Aqua: 147 tiles → cubes of 43, 33, 20, 20, 19, 12
  • Magenta: 87 tiles → cubes of 52, 35
  • Navy: 14 tiles → cubes of 14
  • Green: 5 tiles → cubes of 5

⚠️ 3 hidden “?” cubes in the tray.

Spoiler: what they hide

Aqua 19, Aqua 33, Aqua 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 Aqua 33 cube.
  2. Send the Jade 27 cube.
  3. Send the Aqua 20 cube.
  4. Send the Aqua 20 cube.
  5. Send the Jade 25 cube.
  6. Send the Aqua 19 cube.
  7. Send the Aqua 12 cube.
  8. Send the Jade 6 cube.
  9. Send the Jade 54 cube. Only ~27 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 Aqua 43 cube. Only ~25 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.
  11. Send the Jade 31 cube. Only ~22 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.
  12. Send the Magenta 35 cube. Only ~20 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 Green 5 cube.
  14. Send the Magenta 52 cube. Only ~18 of its 52 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
  15. Send the Jade 48 cube. Only ~24 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.
  16. Send the Jade 40 cube. Only ~20 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.
  17. Send the Navy 14 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.
