40 Lines Tetris Sprint
Clear 40 lines as fast as possible. Sprint mode uses millisecond timing, local best storage, replay events for recent runs, and a result card with speed, holes, stack danger, and a drill suggestion.
Settings
Clear 40 lines fast
Sprint changes the feel of the puzzle. You are not trying to survive forever; you are trying to clear exactly forty lines with the fewest delays. Clean stacking is still important, but speed and decisiveness matter more than in Marathon. A messy recovery that wastes fifteen seconds can cost the run even if it avoids game over.
What the result card shows
When the challenge completes, the result card shows elapsed time, pieces placed, speed in pieces per second, holes, highest stack danger, and the most useful drill for the next attempt. Recent replay events are stored locally so future versions can provide a ghost or replay viewer without sending move-by-move data to analytics.
Sprint practice tips
Start with clean surfaces and simple wells. Avoid placements that require several cleanup pieces unless the next queue already contains those pieces. Use hard drop confidently, but keep misdrop protection on when playing on a phone. If your time stalls, practice twenty-piece survival before chasing a record again.
