You should make chess/checkers/pool table/foosball table interact to play with a max of 2 players on chess/checkers and a max of 4 on pool and foosball. Would be a awesome idea. I would probably be stuck in my condo the whole time if you can wage against your friends too! Winner gets all the money.
P.S. Could try adding a card dealer table for card games. Like 13 / black jack / gold fish … etc
again to wager with your friends .
