As requested, reposting my links post for various simulators.

BBO Dealer.

Henk Uijterwaal's dealer seems to have been new-site-name-broken, but there is an (untested! I just saw a link!) "improved" version of it.

Thomas Andrews' Deal, if you want to learn Tk.
anntzer's Redeal (port of TAndrews' Deal), if you want to learn Python.

Both are somewhat cumbersome to understand the formatting (for more than basic work), but after you do understand it, it's *very easy* to build new sims.

DO NOT USE ANY OF THESE TO MAKE DEALS FOR COMPETITION.
They are *not* completely random, nor cryptographically secure (hence could be compromised).

Use BigDeal instead.

Seriously. Don't even think about anything else. If it's good enough for the world championships, it's good enough for you.
