How to play
Press and hold to trace the ghost triangle outline in one stroke. The score measures side length equality, angle sharpness, and how cleanly you close the shape.
Tip: keep the three sides as equal in length as possible — that's what separates a 70% from a 90%.
Frequently asked questions
Trace all three sides of the ghost triangle in one continuous stroke, keeping each side equal in length and each corner sharp, then close back to your start. Equal sides are what separate a 70% from a 90%.
An equilateral triangle needs three equal sides and three 60° corners at once. Keeping the sides the same length by hand while hitting sharp angles is what makes the perfect triangle test difficult.
Most players score between 70% and 85%. A score above 90% is excellent and leaderboard-worthy because equal sides and clean corners are hard to nail freehand.
