Colony Flow! Level Walkthroughs & Solutions

Colony Flow! by ABI Games hides a pixel picture under a wall of coloured blocks. Below it sit five empty slots and a stack of numbered ant boxes. Tap a box from the front row and it slides into a slot; its ants stream up to the picture, pick off blocks of the same colour from the outside edge and haul them back to the nest. The number on the box is how many blocks that colony will carry, and it counts down with every trip. When it reaches zero the box leaves and the slot is free again.

The catch is reach. Ants only take blocks they can get to from the edge, so a colour that is still buried under other colours sits in its slot doing nothing. Fill all five slots with stuck boxes and the level is over. Deeper rows of the stack stay locked until the row in front is used, grey question-mark boxes hide their colour until they reach the front, and later levels add linked pairs that need two slots at once, padlocked boxes opened by keys hidden in the picture, and the occasional countdown. The order you open boxes matters more than speed.

These habits carry across every level. Open any walkthrough for board-specific moves.

• Read the picture from the outside in: the colours on the edge are the only ones ants can carry right now.
• Match the number on a box to the blocks you can see. A 30 box for a colour with 4 exposed blocks will sit in a slot until the rest are uncovered.
• Keep one slot free at all times. Five stuck boxes is the only way to lose, and it usually happens two moves before you notice.
• Open the front row of the stack to unlock the rows behind it, but only when the slots can absorb what comes out.
• Treat question-mark boxes as a gamble: bring one to the front while you still have spare slots, not when you are down to your last one.
• Finish the outer ring of the picture before chasing inner detail; each ring you strip exposes the next set of colours.
