What You're Up Against

Level 680 paints Rainbow with 388 tiles across 5 colors, split into 13 cubes in the tray. You have 5 waiting slots and two nest holes.

  • Cream: 102 tiles → cubes of 39, 32, 31
  • Blue: 86 tiles → cubes of 43, 23, 20
  • White: 74 tiles → cubes of 49, 25
  • Black: 66 tiles → cubes of 45, 21
  • Teal: 60 tiles → cubes of 23, 21, 16

⚠️ 2 hidden “?” cubes in the tray.

Spoiler: what they hide

Teal 21, Teal 16

🔒 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 Black 21 cube.
  2. Send the Teal 16 cube.
  3. Send the Black 45 cube. Only ~27 of its 45 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 White 25 cube.
  5. Send the White 49 cube. Only ~28 of its 49 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 Cream 39 cube.
  7. Send the Cream 32 cube.
  8. Send the Cream 31 cube. Only ~27 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.
  9. Send the Blue 23 cube.
  10. Send the Blue 20 cube.
  11. Send the Blue 43 cube. Only ~31 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.
  12. Send the Teal 23 cube.
  13. Send the Teal 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.
