Summit Lock
A deliberate climb, one lock at a time
How to play
Reach the summit by clearing eight rows, making at least one double-row clear, and leaving a stack no taller than four cells. All three conditions must hold; you may keep climbing after eight rows. Limit: 40 placements. Alpine rank takes 18 or fewer placements, Summit 26, otherwise Trail.
Each shape grants two free clockwise rotations. Unused rotations and cleared rows become rope (maximum six). Extra rotations cost one rope; a reserve exchange costs two and can be used once per shape. Reserve does not refill free rotations. Save points for future awkward pieces, or spend rope to bring a useful shape forward. The three-shape forecast and faint landing ghost show your plan before commitment.
Tap a column, Rotate, then Drop. O is a square, I a bar, T a fork and L an elbow. Blocked drops spend nothing. No reachable orientation or reserve ends the climb. Arrows aim; Retry repeats the same shapes; New climb changes them.
