Decent replication.
You've managed to get the basics of Poker down, so you got average points for creating a decent flash copy of the game and a few extra for betting. The 'World Leaders' theme was a nice touch, though I'd suggest offering a greater variety, perhaps cycling different leaders in when the player reaches higher levels of play?
That brings up the main problems I had with this, and things that might have made it fun enough to earn a tend if they hadn't gotten in the way by not being there. High Rolling is no fun at all. I managed to get some good rolling down, working my way up to the $50K range. At this point:
Waiting for your winnings to dole out or simply trying to bet larger amounts of tokens takes way too long (1 click for every $100).
1. You really NEED to have larger denominations of betting chips, $100, $500, $1000, $10K, $100K, and so on.
2. The other half of that problem is that you need to add an instant calculator rather than ticking off the chips one at a time. It's fairly quick at lower levels of play, but the wait gets annoying at the higher levels.
3. A cap on the winnable amount, so that players can break the bank. Infinite winning is a good ego-stoker, but rather boring.
