A water column game that includes a plurality of vertically oriented water columns, each having a housing disposed at the upper end thereof coaxial with and in open communication with the column. A float is freely disposed and captured within each housing. A target and valves are responsive to a game player for directing water into a lower end of each water column, such that water rises within the column and the housing in sequence so as to raise the float buoyantly within the housing. A switch is disposed at the upper end of each housing, and is responsive to contact by the float for indicating that the float has reached the upper end of the column. After each play, all water columns and housings are drained to a common sump. The water-fill volume of each column and housing is adjustable and all columns are fed from a common pump for equalizing the opportunity of each player to win.
