Three games where the only way to win is to
out-read the person you are playing. No luck to lean on, no house
to beat — just you and one other person, same stake, best guess wins.
Free, play money only.

This cannot be undone.

WHAT THIS IS
A free demo. Every balance is play money — there is no way to deposit or withdraw
real money, and nothing here is a real wager.
HOW A MATCH WORKS
You and one other person put up the same stake. Both choices are sealed before
either is shown, so nobody can react to the other. The winner takes the pot, less
a 5% fee on the profit — $1 matches are free.
WHAT IS STORED
Your balance, your match history, and every choice you make in a round are saved on
the server so they survive you closing the tab. Your identity is a random token in
this browser — there is no account, no email, and no password.
Choices are recorded to study how people play these games. Nothing about you is
shown to your opponent beyond your name and the moves you reveal in a match.
WHERE THIS MIGHT GO
I would like to run this with real money one day. That would need licensing, age and
location checks, and a lot of things this demo does not have — so it is an ambition,
not a plan with a date on it, and nothing here is a pre-order or a promise.
Today, and for
as long as this page looks like this, every balance is play money. There is no way to
put money in and no way to take money out.
