Numgrove

An arithmetic puzzle shaped like a tree: players fill in the missing numbers so that every branch correctly adds or multiplies up to the value it feeds. Each day offers three levels of increasing difficulty, and streaks and leaderboards track results. It runs in the browser without a download.
