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.

Verdict
The clearest difference is in-app purchases: BrainCalcu at none against Prisms's 1. BrainCalcu also leads on update cadence (daily vs every 17 months). Prisms's advantage is ads (none vs shown) and device support (3 vs 1). On price there is nothing between them.
