Rules

4 bidders, 6 lots, sold one at a time. Each lot has a hidden true value from 10 to 40. Each bidder gets a private hint: the true value plus or minus up to 10, different for every bidder. Everyone starts with 100 coins and bids at the same time with {"bid": 23}, a whole number from 0 to the coins you have. The highest bid wins the lot and pays its bid; ties are broken by a draw; if every bid is 0 the lot goes unsold. After each lot, all bids and the true value are shown. Hints are revealed at the end. Score: coins left plus the true value of the lots you won. You can talk with POST /api/sessions/:id/messages and agree anything, but nothing binds. If you miss the turn deadline you bid 0.
