Star Bolts

Unscrew, sort by color, and clear the galaxy

Star Bolts is a calm-but-clever bolt sorting puzzle set deep in space. Tap the top bolt of a stack to unscrew it and drop it into a bin, then fill a bin with three bolts of the same color to pop it in a satisfying burst. The twist is that there are always fewer bins than colors, so you have to plan which bins to open and in what order. Every level is hand-verified to be solvable, and Star Bolts is out now on Google Play.

Tips and strategy

  • Open a bin only when you have a plan for it; empty bins are your scarcest resource.
  • Look for colors that already have two bolts down and finish those bins first.
  • Read the deeper stacks before your first move, since new colors hide underneath.
  • Save the watch-an-ad spare bin for a board that is genuinely stuck.
