Three triangles

Three Triangles strips puzzling down to its purest form: three simple shapes, one elegant goal. The game presents you with a trio of triangles that must be arranged to create a perfect larger triangle. Each piece can be rotated, but the real brainwork comes from figuring out how their angles and side lengths interact. There's no clutter, no timer, just you and the geometry. What starts as a seemingly easy task quickly reveals its depth. The satisfaction comes from that moment when the edges click into place, and the three separate pieces become one harmonious whole. It's a silent, meditative exercise in spatial reasoning that'll have you thinking in angles and symmetry long after you close the tab.

What is Three triangles

Three Triangles is a pure spatial-reasoning puzzle that asks you to assemble three pieces into one perfect triangle. It's minimal, meditative, and surprisingly tricky.

How to Play

Rotate each triangle by clicking or dragging the rotation handle, then drag pieces onto the board. Position them so their edges meet exactly, forming a larger triangle with no gaps or overlaps.

Tips for Playing

  • Start by identifying which sides of each triangle are equal in length.
  • Rotate the largest piece first to establish the approximate outline.
  • Use the alignment guide to snap edges into place for perfect contact.
  • Work from the base upward; a solid foundation stabilizes the rest.
  • If stuck, rotate a piece 180 degrees—mirror angles often fit unexpectedly.

Frequently Asked Questions

What is the goal of Three Triangles?

You need to rotate and position three triangular pieces so they combine into one single larger triangle, with all edges flush and no overlap.

How do I control the pieces?

Click or drag to move a triangle, and use a rotation control or right-click to spin it. The game may offer snapping guides to help align edges.

Are there different levels or just one puzzle?

The core gameplay involves a single arrangement, but solving it cleanly is the challenge. Some versions may include variations or timed modes.

Is there a time limit?

Generally, no—Three Triangles is about careful thinking, not speed. Take your time to analyze angles and sides.

What happens if I overlap the pieces?

Overlapping isn't allowed; the pieces must meet only along edges. If they overlap, the solution isn't valid, so adjust their positions.

Can I reset the puzzle?

Yes, there's typically a reset button that returns all triangles to their starting positions, letting you try a fresh approach.
