About Sparkspan: Matchstick Architect
Step into a pocket workshop where numbers are made of wooden beams. Lift and relocate matchsticks until a broken addition becomes true. Seventy-five seeded puzzles, one-, two-, and three-move challenges, undo, and guided hints create a tactile 3D arithmetic brain teaser.
How to Play Sparkspan: Matchstick Architect
The wooden seven-segment digits form an incorrect addition equation. Move matchsticks to make all three digits valid and the addition correct. Tap a bright beam to lift it, then tap a faint slot to place it. Easy allows one move, Medium two, and Hard three. A move is one lift plus one placement; the same total number of beams must remain. Undo reverses a move, and Hint marks the next beam in a known solution. Solve 75 seeded puzzles with mouse or touch.
