What You're Up Against
Level 421 paints Pizza with 248 tiles across 4 colors, split into 10 cubes in the tray. You have 5 waiting slots and two nest holes.
- Aqua: 130 tiles → cubes of 43, 40, 25, 22
- Blue: 92 tiles → cubes of 40, 27, 21, 4
- Yellow: 23 tiles → cubes of 23
- Jade: 3 tiles → cubes of 3
⚠️ 1 hidden “?” cube in the tray.
Spoiler: what they hide
Yellow 23
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 Blue 40 cube.
- Send the Blue 27 cube.
- Send the Aqua 25 cube.
- Send the Aqua 22 cube.
- Send the Blue 4 cube.
- Send the Aqua 43 cube. Only ~21 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.
- Send the Jade 3 cube.
- Send the Blue 21 cube. Only ~15 of its 21 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 40 cube. Only ~19 of its 40 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 23 cube. Only ~20 of its 23 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.
