What You're Up Against
Level 520 paints Pizza with 248 tiles across 4 colors, split into 9 cubes in the tray. You have 5 waiting slots and two nest holes.
- Blue: 130 tiles → cubes of 52, 39, 27, 12
- Teal: 92 tiles → cubes of 53, 20, 19
- Yellow: 23 tiles → cubes of 23
- Brown: 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 Teal 20 cube.
- Send the Teal 19 cube.
- Send the Blue 12 cube.
- Send the Teal 53 cube. Only ~31 of its 53 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 27 cube.
- Send the Blue 52 cube. Only ~32 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 Brown 3 cube.
- Send the Blue 39 cube. Only ~21 of its 39 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.
