Swipepi

Swipepi is a casual yet clever puzzle game built around the idea of filling a board with one continuous, uninterrupted line. You begin with a single light-colored block and gradually paint the entire grid in a rainbow gradient. Each move extends your line in a chosen direction until it hits something: either the edge of the board, a filled cell, or a blocker – depending on what it meets first in its path.

This straightforward mechanic is enriched by a few other crafty ones: portals teleport your active cell across the board, and some blockers must be hit a set number of times before being cleared. The levels can be approached in a logical manner rather than brute-forcing your way to a solution, as your possible moves are limited at every step (you can move in a maximum of four directions). Additionally, the level layouts are usually designed to guide you toward reasoning out the solution instead of endlessly trying combinations

On Android, the game is free-to-play but comes with several restrictions. You’ll need to watch ads every four levels or for unlocking a new skin for your starter block. You only receive three hints and three undos for the entire game unless you purchase more through in-app purchases. On some other platforms, Swipepi is limited to 100 levels, with no way to gain more hints or undos after the initial three.

The Steam version is essentially a premium port that removes all these limitations. Every cosmetic is unlocked from the start, hints and undos are unlimited, and there are no in-app purchases at all. Instead, the game is offered at a one-time price of $2.99. It includes 500 handcrafted levels that are relaxing, thoughtfully designed, and usually take only seconds to solve. This makes Swipepi perfect for short play sessions in between other activities. Steam achievements are planned to be added soon.
