Stillpoint III: Glide

A calm symmetry puzzle where one flick sends a stone gliding until the board edge or another stone stops it. Arrange and turn the colored stones to mirror the center seam.

▶ Play Stillpoint III: GlideFlick one stone to glide - tap a stone to turn it

Mirror the center seam

Make the right half of the board reflect the left half. A pair matches only when both spaces hold the same shape and color, with directional shapes facing as mirror images. Matching pairs glow softly. Empty spaces must mirror empty spaces too.

Flick one stone through the open cells. It stops in the last empty space before the slate blocker, while every other stone stays put.
One flick moves one stone
Flick an occupied space up, down, left, or right. That stone glides as far as it can and stops immediately before the board edge or the next stone. You cannot choose a shorter stopping point, and a stone blocked at the start does not move or spend a turn.

Use stones as movable walls

Unlike Currents, the other stones remain still during a glide. Their positions determine where the moving stone can stop, so a useful blocker may matter even when it is not yet in its mirrored home.

Dot: matches by position and color. It has no facing, so tapping it does not spend a move.
Half stone: tap to turn it one quarter-turn clockwise. Its flat and curved sides must reflect its partner.
Quarter stone: arrives as difficulty rises. Tap to rotate it clockwise until its corner mirrors the matching stone.
Mirror pair: same shape, same color, opposite-facing orientation across the vertical seam.

Use the solver and Undo together

Every new puzzle is verified
The game solves each generated board before showing it. The Guide searches your current position and highlights a stone, then shows whether to turn or flick it. A later move can still create a position with no route, so use Undo when the Guide reports that no path was found.

Undo restores the previous board and move count, up to the recent history kept for the puzzle. New Stonescreates another verified puzzle at the current difficulty. The sound button toggles the soft turn, glide, and harmony tones.

Solving efficiently raises the hidden difficulty level; taking many more moves than the shortest verified route can lower it. Boards grow from four by four to five by four and finally five by six. Quarter stones and up to four colors join gradually. After harmony appears, the next puzzle begins automatically and one garden dot is added, with up to fourteen dots shown.

Tips

  • Before flicking, trace the lane all the way to its first blocker.
  • Build temporary stopping points when a target cell has no wall behind it.
  • Move a blocking stone only after checking which other glides depend on it.
  • Use Undo as soon as the Guide says the current position has no path.
  • Check orientation last when a stone has reached its mirrored position.
