Puzzle Storm is a timed run. Puzzles start easy and get harder as you keep solving; a wrong answer moves you straight to the next position rather than letting you retry. There are three formats: a three-minute run, a five-minute run, and survival, which has no clock and ends on your first mistake.
Solving quickly earns time back. Reaching a combo streak adds seconds to the clock, so a clean run extends itself and a run with scattered errors runs out early. That is the core tension of the mode — accuracy buys you time, and rushing costs it.
Under a clock you cannot calculate every line to the end, so you are forced to rely on recognition: seeing that a position contains a back-rank weakness or a loose piece before you have worked out the moves. That is a genuinely different skill from calculation, and it is the one that decides most fast games.
It also exposes a gap that untimed training hides. A pattern you can find in ninety seconds but not in five is not yet learned in a way that helps you in a real game with a ticking clock. Storm makes that gap visible, which is uncomfortable and useful.
Look at forcing moves first — checks, captures, threats. Under time pressure, scanning quiet moves is almost always wasted effort, because puzzle solutions are forcing by construction.
Do not fight a position you cannot see. A wrong answer costs one puzzle; thirty seconds spent staring costs several. If nothing appears within a few seconds, play the most forcing candidate and move on.
Expect the difficulty to pass your level. Storm keeps raising difficulty as you solve, so every run is designed to end in positions you cannot solve. Ending on a hard puzzle is the mode working, not a bad run.
Storm is recognition speed. It works best next to something that builds depth: rated puzzle training, where puzzles are matched to your rating and there is no clock, or Woodpecker training, which repeats a fixed set until the patterns become automatic.
If the same motif keeps ending your runs, mistake training and a Profile Report will show whether it is also costing you rating in real games.
