What Is Reborder?
Reborder is a geography puzzle built around the shared boundary between two neighboring countries. Each round gives you their names and a combined outline. The dividing line is missing, and your task is to put it back.
That small gap can change how familiar a map looks. You may recognize both countries yet struggle to remember where their border bends or meets the coast. Reborder turns that uncertainty into a drawing challenge, followed by a clear comparison with the answer. The outer shape gives you clues; your memory fills in the line.
How to Play Reborder
1. Study the two countries
Start today's challenge and look at the country names and shared silhouette. Before drawing, picture where each country sits within the outline. Look for coastal corners, narrow sections, and changes in shape that might help you place the missing boundary.
2. Draw the border
Use your mouse or finger to draw the border between the countries. Reborder supports multiple strokes, and your line can start outside the map. Zoom in for a closer look, or reset your drawing before submitting if you want to try a different shape.
3. Submit and compare
Submit your line to reveal the correct border and receive a score out of 100. Reborder scores both how closely your drawing follows the boundary and how much of it you cover. Check the comparison to see where your line drifted or ended too early.
4. Finish your challenge
Complete all four rounds to get your daily average. Review the borders, copy your result to share with friends, and check the leaderboard. Each Reborder round is a chance to notice a bend, endpoint, or proportion you can remember next time.
Why Play Reborder?
Reborder gives map knowledge a practical test: can you turn a remembered border into a line? Familiar places become fresh puzzles when the boundary disappears. Every answer comparison gives you something specific to look at, whether you missed a gentle curve or placed the whole border too far east.
The daily format makes Reborder easy to return to, while Unlimited gives you room to practice. Play for a better score, a friendly comparison, or the pleasure of recognizing a shape that once surprised you.

Tips for a Better Reborder Score
Start with the endpoints. Decide where the shared border should meet the outside outline, then connect those points with the main bends. In Reborder, a carefully placed line gives you a better starting point than a rushed collection of guesses.
Use zoom when a small curve is difficult to judge. Aim to cover the full boundary, then study the answer after submitting. Practice one region in Unlimited to become familiar with neighboring shapes. Review each Reborder result carefully, and note the bends or endpoints you missed.
