Nodolus vs PRISM

Nodulus is a puzzle game with a clever twist. Based on the mathematical theory behind plank puzzles, consists of a grid of cubes and rods which can be rotated with a swipe. Turn the activated cubes to reach the end cube and win the level.

Turn a mirror and the light finds a new path. Guide the beam through every gem, then into the exit. There is always exactly one true answer. PRISM is a quiet logic puzzle made of light and mirrors. Tap a mirror to flip it between "/" and "\", route the laser through every glowing gem, and land it in the exit to win. The beam redraws instantly with every tap, so you can test ideas and watch them play out. Decoy mirrors that aren't part of the solution create convincing wrong paths, so tapping around won't get you there. FEATURES - One-tap controls: just rotate mirrors - Every board has exactly one solution path, so it's logic, not luck - Four difficulty levels (8x8 to 11x11), from gentle to brutal - A daily puzzle with a solving streak - 16 achievements, plus a clear celebration for personal bests and badges - Stats for solves, average time, and no-hint rate - Board color themes: Sky, Gold, Indigo, Jade, and Sakura - No account needed, and it plays offline - English and Japanese GREAT FOR - Turning a commute or coffee break into ten minutes of focus - Fans of logic puzzles that reward reasoning - Anyone who finds most puzzle apps too easy - People who like calm, minimal design - A one-puzzle-before-bed ritual PRIVACY Your progress stays on your device and is never sent anywhere.
