Share a Shikaku Challenge
Choose the fast official route or build a custom puzzle of your own. Either way, you can send one clear Shikaku challenge link for someone else to open and play.
Pick the Right Way to Share
Want the quickest option? Start with an official Shikaku challenge. You can browse curated boards, copy the link, and send a puzzle in seconds. Want something more personal? Use the custom builder to choose the board size, the difficulty, and a few extra details before you share.
Why Share a Shikaku Challenge?
A shared challenge turns a solo logic puzzle into a small invitation. It gives your friend the same board, the same starting point, and a cleaner reason to jump in. It is a simple way to compare times, send a thoughtful puzzle, or keep a small puzzle habit going with someone else.
Official or Custom?
Pick an official challenge when you want a fast, ready-made puzzle with no setup. Create a custom challenge when you want more control over the board size, the difficulty, the timer, or the message that comes with the puzzle. Both routes lead to a single challenge link that is easy to open and easy to share.
What Happens After You Share?
When someone opens your link, they land on the same challenge instead of a random puzzle. They can play it directly, compare the experience with you, and come back to try again. Over time, the challenge library can also grow into a better place to browse featured boards, popular picks, and community-worthy puzzles.
