Chipfall is a two-player strategy game that combines the classic four-in-a-row grid with a secret bidding system. Instead of alternating turns, players compete for the right to move by placing hidden bids with their chips. Each player begins with 1,000 chips; both secretly bid each turn, the highest bidder drops a token, and the first to line up four in a row wins. Outbid, out-think, align four.
