What You're Up Against
Level 405 paints House with 276 tiles across 5 colors, split into 9 cubes in the tray. You have 5 waiting slots and two nest holes.
- Brown: 100 tiles → cubes of 54, 46
- Dark: 78 tiles → cubes of 41, 34, 3
- Indigo: 60 tiles → cubes of 31, 29
- Pink: 20 tiles → cubes of 20
- Lime: 18 tiles → cubes of 18
⚠️ 1 hidden “?” cube in the tray.
Spoiler: what they hide
Indigo 31
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 Indigo 31 cube.
- Send the Dark 3 cube.
- Send the Indigo 29 cube. Only ~27 of its 29 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Dark 41 cube. Only ~24 of its 41 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Brown 46 cube. Only ~26 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 Brown 54 cube. Only ~15 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 Dark 34 cube. Only ~20 of its 34 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Lime 18 cube. Only ~16 of its 18 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Pink 20 cube. Only ~14 of its 20 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.
