What You're Up Against
Level 257 paints Donut with 208 tiles across 4 colors, split into 6 cubes in the tray. You have 5 waiting slots and two nest holes.
- Jade: 88 tiles → cubes of 50, 38
- Violet: 86 tiles → cubes of 54, 32
- Magenta: 24 tiles → cubes of 24
- Black: 10 tiles → cubes of 10
⚠️ 1 hidden “?” cube in the tray.
Spoiler: what they hide
Magenta 24
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 Jade 38 cube.
- Send the Jade 50 cube. Only ~42 of its 50 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Violet 54 cube. Only ~31 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 Black 10 cube.
- Send the Violet 32 cube. Only ~22 of its 32 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Magenta 24 cube. Only ~12 of its 24 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.
