The top hundred
Every rating starts at 1000 and only moves when two signed-in accounts duel each other. Beating somebody rated as you are is worth ten points either way — and twenty while your rating is still provisional, which it is until twenty rated duels are behind it. Beating somebody rated far above you is worth more, and beating somebody far below you is worth almost nothing. Neither is beating the bot, and neither is beating the same person all evening.
