What You're Up Against
Level 309 paints Swan with 484 tiles across 5 colors, split into 17 cubes in the tray. You have 5 waiting slots and two nest holes.
- Jade: 231 tiles → cubes of 54, 48, 40, 31, 27, 25, 6
- Aqua: 147 tiles → cubes of 43, 33, 20, 20, 19, 12
- Magenta: 87 tiles → cubes of 52, 35
- Navy: 14 tiles → cubes of 14
- Green: 5 tiles → cubes of 5
⚠️ 3 hidden “?” cubes in the tray.
Spoiler: what they hide
Aqua 19, Aqua 33, Aqua 12
🔒 1 locked cube — free the cube above them before they can be picked.
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.
