What You're Up Against
Level 900 paints House with 276 tiles across 5 colors, split into 10 cubes in the tray. You have 5 waiting slots and two nest holes.
- Black: 100 tiles → cubes of 49, 28, 20, 3
- Blue: 78 tiles → cubes of 52, 26
- Red: 60 tiles → cubes of 42, 18
- Orange: 20 tiles → cubes of 20
- Navy: 18 tiles → cubes of 18
⚠️ 1 hidden “?” cube in the tray.
Spoiler: what they hide
Red 18
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 Black 20 cube.
- Send the Red 18 cube.
- Send the Black 3 cube.
- Send the Red 42 cube. Only ~36 of its 42 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 52 cube. Only ~24 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.
- Send the Black 49 cube. Only ~21 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 Black 28 cube. Only ~11 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.
- Send the Blue 26 cube. Only ~14 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.
- Send the Navy 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 Orange 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.
