DriftSea is a free online sliding puzzle game where you move floating bars across an ocean-themed grid to hit specific targets in each level. The core mechanic is straightforward – bars glide smoothly until they hit an obstacle – but the real challenge comes from planning several moves ahead before committing to anything. Every slide counts, and a single careless move can lock you out of the solution.

What keeps DriftSea interesting is how each new level reshuffles the layout and adds fresh complexity without overcomplicating the rules. You are always working with the same basic mechanic, but the grid configurations force you to think differently every time. The clean ocean visuals and calm sound design keep things relaxed while your brain works through the logic. There are no timers or penalties, so you can take your time and experiment freely until the solution clicks.

DriftSea is a great pick for fans of block sliding puzzles, casual brain teasers, and grid-based logic games. If you enjoy games like unblock or rush hour style puzzles, this one fits right in. It works well as a free puzzle game with no download on any browser, making it easy to jump in during a short break. Players searching for relaxing puzzle games online, ocean-themed brain games, or waterslide grid puzzles will find exactly what they are looking for here.
