Fish Sort
Fish Sort is based on a very clear sorting rule, but it requires a real method to go all the way. First, you move fish between several algae branches to bring those of the same color together in the same place. Then you must respect the essential constraint of the game: a fish is accepted only on an empty spot or on an identical fish. The objective is reached only when everything is correctly sorted. This base seems simple, otherwise the first levels would not be so accessible, yet the difficulty rises because each new step adds more colors, more possible combinations and therefore more chances for error. You must read the overall layout before acting, identify what can be moved without consequence and what must wait.
The heart of the game lies in your decisions. You aim to create space, keep options open and avoid the moment when no useful transfer is possible. An almost full branch can become a solution if it receives the right color, or a trap if you occupy it too early. Likewise, quickly gathering a few identical fish is not always the best choice, because it may doom another indispensable transfer a little later. The game therefore asks you to reason in the correct order, to build progressive groupings and to correct your strategy when a dead end appears. Each level varies by its layout and by the sequences it allows, which renews the thinking without changing the final objective. Have fun!
