Colors are relaxing and non-stimming before bed. Good for sleepless nights. 👍👍 ### 5/5 — 🥲 *2025-01-09, version 1.1.2* It’s very pretty and very frustrating, which, distressingly, I find very appealing ### 5/5 — Great game *2024-05-10, version 1.1.2* Well-designed puzzles and a beautiful interface! ### 5/5 — Fun and smart! *2024-02-16, version 1.1.2* Very fun once you get the hang of it.

The colors, design, and music are soothing, as well. My first time playing I completed stages 1 and 2. Looking forward to continuing. The puzzles remind me of Sudoku and a game called Flow Free. Two of my favorites. Cardinal offers a new combined twist to these. If you like Flow Free, you’ll definitely like this game. ### 5/5 — Great app *2021-02-22, version 1.1.2* Very fun and very relaxing!!! ### 5/5 — V fun v chill *2021-02-20, version 1.1.2* Great game to zone out and take a break from the day with. ### 5/5 — Sudoku but Make It Aesthetic *2021-02-19, version 1.1.2* Love this!
