A sequence of symbols follows a hidden rule and you must tap the next element in the pattern from four options. Rules shift between rounds — arithmetic progressions, shape rotations, colour cycles, and spatial transformations. A wrong answer reveals the correct rule briefly before the next sequence loads. Identify fifty consecutive patterns correctly to earn the master logician title.

A magician shuffles cards rapidly and you must track a specific target card through all the movement and misdirection. The shuffle grows faster and the magician adds new cards to confuse. Tap the target card the moment the shuffle stops. Three wrong identifications end the trick permanently. The magician performs more complex shuffles in later rounds that defeat even trained eyes.

Swipe blocks across a grid to merge matching numbers and build higher and higher values. Two 2s become a 4, two 4s become an 8 — the progression is simple and addictive. The grid fills with each swipe until there are no valid merges left. Later grids introduce colour-coded blocks that only merge with their own colour, adding a spatial planning dimension to the arithmetic challenge.
