How can I make it really difficult to bot a multiply tetris game?
<p>I thought about making a multiplayer tetris game using web technologies. However, as the source code is very public when writing a web-based JavaScript/HTML5 game, it would be fairly simple to program a bot to play a near perfect game. So, how could one make it really difficult to bot a tetris game?</p>

<p>I figured, that I could do something fancy like running the game entirely on a server and stream the game as a video using HTML canvas, but this will still be fairly simple to write a bot for, I would presume.</p>

<p>What sort of thing could I do to make it difficult to write a bot for this game, multiplayer tetris?</p>
