Coloruid 2 continues the flood-fill puzzle of the original with new layouts and stricter move budgets. The rule is unchanged — recolour your region, absorb adjacent regions of that colour — but the levels are built to punish greedy play more consistently.
The sequel's levels tend to have a single intended sequence rather than several workable ones, so it plays more like a puzzle to solve than a board to optimise.
Same flood-fill rule with new layouts and tighter move limits, and levels designed around a single intended solution rather than several workable ones.
Plan the full sequence first, prioritise colours that connect distant regions, and leave the most common colour until last so it merges the maximum area in one move.
Yes — tap a colour. Nothing to install.
