Guriddo
Guriddo is a free mobile puzzle game built around Stradoku, a daily number grid challenge that mixes ideas from Sudoku, Kakuro, and Nonogram puzzles. The flagship app ships fresh competitive puzzles each day, and guriddo.app also links to sibling titles like Rumba, Hoshi, Akari, Patches, Lofi Sudoku, and Tawa. It is a gaming pick for people who want logic grids on their phone rather than a browser toy.
Most puzzle apps stick to one format. Guriddo’s publisher splits each style into its own app, so Stradoku fans get a focused daily ritual while Hoshi handles Star Battle grids and Lofi Sudoku bundles four Sudoku variants including a 6×6 Mini mode. That split means you download only the mechanics you want instead of wading through a bloated puzzle hub.
The apps are free on iOS and Android, with store ratings of 4.8 on Apple and 4.7 on Google Play for the main Guriddo title. Casual players can treat each day as a quick brain warm-up, while leaderboard-minded solvers can chase daily scores. If you already burn through mainstream Sudoku books, Stradoku’s hybrid rules are the hook worth trying first.
