Tropical fish dart through a vivid coral reef and you tap each one before it escapes through the gaps in the reef wall. Clownfish score one point, angelfish score three, and a rare blue tang drifts across the screen only once every five waves and is worth ten. Jellyfish drift in from the deep and cost a life if touched — give them a wide berth.

Constellations form across the night sky one star at a time and you draw connecting lines between them to weave the pattern before dawn erases it. Each constellation has a unique shape — some simple triangles, some sweeping arcs of twenty stars. Weave a perfect constellation without a wrong line and a shooting star streaks the sky for a massive bonus.

A moving platform slides back and forth above your growing tower and you tap to drop it onto the stack below. Any overhang is sliced off — leaving a narrower block for next time. The platforms shrink progressively as the tower rises into the clouds and beyond into orbit. A perfect drop restores your last lost sliver. How many floors until you reach the stars?
