This is the first in a weekly series of features dedicated to highlighting interesting, lesser known hidden gems across iOS and Android. With the sheer volume and rate of new releases, it can be easy for a game to unnoticed, unseen; some here may be newer or older, but all are engaging in their own unique way.

Picross, Paint It Back, Minesweeper, Hexcells. There’s something uniquely satisfying about a logic puzzler, perhaps how one can solve their challenges without guessing or mistakes, through pure deduction. RYB falls squarely in this category, a Picross-style puzzle game that eschews numbers and grids for colors and geometric shapes.

Squares, triangle, hexagons, and other shapes form abstract levels far more vibrant and differently structured than similar games. But despite RYB’s aesthetic, the core concept remains: use logic and clues to correctly fill in each shape with the right colors.

The game gradually introduces its assortment of mechanics and rules but levels soon evolve from a group of shapes and colors into a visual language you can decode and decipher. Being able to study one of RYB’s kaleidoscopic stages, “read” the markers and hues and shapes, and meticulously fill its interior with the right colors without a single guess is a satisfying process that remains compelling throughout.

Between its colorful style, visual learning, challenging yet fair mechanics, RYB proves to be a cleverly-designed puzzler. If RYB's colorful minimalism seems intriguing, you can find it on the App Store for $2.99.
