Best Counting Discord Bots

A counting bot watches one channel, checks that each message is the next number, and deletes or resets when someone gets it wrong. The rules are where they differ: some block the same person counting twice in a row, some accept math expressions, and some keep a high score and a save point so one mistake does not wipe months of progress.

Give it Manage Messages in that channel only, since deleting wrong entries is the whole job. Then check whether the count survives a bot restart, whether there is a leaderboard or a fail role, and whether streak saves are free. Restricting the bot to the counting channel also keeps it from reacting anywhere else in the server.
