Dr. Cubit is an underfunded, genius, zany scientist on the leading edge of cube-based research. As his intern, you can earn his satisfaction by assisting with scientific research in the form of rolling around cubes, attaching different shapes to your cube, then orienting your cube correctly to match up with shaped gates. During your internship, you will encounter 3 different shapes. The circle and square can be placed in any direction, while the triangle must be oriented correctly. You may also encounter teleporters and flooring that’s only temporarily visible, requiring additional spatial reasoning.

Digital Sudoku is a Sudoku variant with a twist: every clue isn't a printed number, it's a partial seven-segment display, the kind you'd see on an old calculator or digital clock. Some segments are lit, some aren't — read the pattern, decode the digit, and place it. Once you're solving, it's classic Sudoku logic all the way down. FEATURES • Three board sizes — 4×4, 6×6, and full 9×9 — each with Easy, Medium, and Hard difficulties (9×9 adds Expert). • A new Daily puzzle every day, with its own streak to keep going. • Stuck? Hint walks you through the next logical step instead of just filling in the answer — you still have to place it yourself. • Undo/redo, a mistake-checking readout, and an optional timer you can show or hide. • Achievements and stats track your solves, streaks, and best times per board and difficulty. • Compare your times on a real per-puzzle leaderboard. • Light and dark themes, both designed around the seven-segment look. • Play instantly as a guest — no account or sign-up required. Whether you're decoding your first 4×4 or chasing an Expert 9×9 streak, Digital Sudoku turns a familiar puzzle into something you have to look twice at.

Verdict
The clearest difference is in-app purchases: Digital Sudoku ⊞ at none against Prisms's 1. Digital Sudoku ⊞ also leads on update cadence (every 8 days vs every 17 months). Prisms's advantage is ads (none vs shown) and ratings volume (19 vs 2). On price, rating, device support and iOS requirement there is nothing between them.
