What You're Up Against
Level 73 paints Fish with 146 tiles across 4 colors, split into 8 cubes in the tray. You have 5 waiting slots and two nest holes.
- Coral: 84 tiles → cubes of 33, 21, 17, 13
- White: 48 tiles → cubes of 30, 18
- Yellow: 7 tiles → cubes of 7
- Indigo: 7 tiles → cubes of 7
⚠️ 1 hidden “?” cube in the tray.
Spoiler: what they hide
Indigo 7
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 Coral 21 cube.
- Send the White 18 cube.
- Send the Coral 17 cube.
- Send the Coral 13 cube.
- Send the White 30 cube. Only ~19 of its 30 tiles are open at this point — park it in a slot and let the surrounding colors clear the rest of the way.
- Send the Coral 33 cube. Only ~18 of its 33 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 7 cube.
- Send the Indigo 7 cube. Only ~6 of its 7 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.
