Crystals pulse with colour on the cave walls and you tap them before their light fades back into the rock. Chains of same-colour taps build a streak multiplier. White crystals freeze all others in place for two seconds — a vital lifeline when the cave starts flashing in rapid-fire bursts. How deep can you mine?

Robot parts tumble down a conveyor belt and you tap each one into the correct slot to assemble your bot before the belt reaches the end. Miss a part and the slot stays empty — an incomplete robot scores half. Rare golden parts upgrade your bot's abilities for the next wave. Build smarter, build faster.

Glowing nodes are scattered across a dark board and you draw a line through them to chain as many as possible in a single stroke. You cannot lift your finger or cross your own path. The longer the chain, the bigger the multiplier. New nodes appear after each chain but the board fills up faster than you expect.
