He means a progressive knockout tournament like on poker stars. The way I do it is each player starts with two bounty chips, then you knock some one out, you get half their bounty chips changed into appropriate cash chips, and the other half get's added to your bounty chips. If the bounty is an uneven number, the extra chip goes for the cash chips. So like lets say it's $10 per buy-in goes to the bounty pool, each bounty chip would be worth $5. Knock out someone with seven bounty chips, three of them get added to your bounty, and four get cashed out for $20 total.
