Frequently Asked Questions
Have another question? Let us know.
How do you score points in Triangles?
You score points by completing a triangle with your line. When you draw the third side of any triangle, that triangle is claimed by you and filled with your color.
Can lines cross each other?
No, lines cannot cross other lines or touch any dot other than the two dots they connect. Each line must be a unique edge between two adjacent dots.
What is the best strategy for winning?
Avoid drawing the third side of an obvious triangle, as this gives points to your opponent. Instead, force your opponent into positions where they have no choice but to give you a triangle. Control the center of the board for more scoring opportunities.
Do triangles with dots inside count?
No, only triangles with no dots inside count for scoring. Larger triangles that enclose other dots do not award points. Focus on closing the smallest possible triangles.
How does the AI opponent work?
The AI analyzes the board state and chooses moves that maximize its own scoring opportunities while minimizing yours. It looks ahead to avoid giving you easy triangle completions.
