What You're Up Against
Level 306 paints Rainbow with 388 tiles across 5 colors, split into 11 cubes in the tray. You have 5 waiting slots and two nest holes.
- Aqua: 102 tiles → cubes of 51, 51
- Blue: 86 tiles → cubes of 54, 26, 6
- Yellow: 74 tiles → cubes of 49, 25
- Coral: 66 tiles → cubes of 46, 20
- Teal: 60 tiles → cubes of 43, 17
⚠️ 1 hidden “?” cube in the tray.
Spoiler: what they hide
Teal 17
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.
- Send the Coral 20 cube.
- Send the Teal 17 cube.
- Send the Blue 6 cube.
- Send the Coral 46 cube. Only ~28 of its 46 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Yellow 25 cube.
- Send the Yellow 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.
- Send the Aqua 51 cube. Only ~42 of its 51 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Aqua 51 cube. Only ~34 of its 51 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Blue 26 cube.
- Send the Blue 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.
- Send the Teal 43 cube. Only ~37 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.
Finish without boosters for 3 stars and bonus coins. If the board jams anyway, a Shuffle or Vacuum booster is the cheapest way out.
