Fishdo

Fishdo is a browser-based puzzle game that focuses on logic rather than speed. It stands out from similar titles because the puzzles strictly require moving pieces along fixed paths rather than placing them freely. The central mechanic is the drag-and-move system, which snaps items into specific slots.

You solve levels by dragging fish and obstacles to their correct locations on the grid. The input works by clicking and holding with a mouse or tapping a touch screen phone, so the interaction feels the same on a laptop or a mobile device. Every turn requires you to decide which piece to shift first to clear a path for the others. There are no power-ups or timers, just you and the puzzle layout.

This game works best for casual players who want to kill ten minutes without learning complex rules. Kids and adults can both pick it up since the difficulty builds slowly from the first level. Tip: Focus on the corners of the grid first, as moving pieces there usually unlocks the center area where the main objective sits.
