PROBLEM TO BE SOLVED: To provide a pachinko island base capable of adjusting discharge of balls as a whole body of a hall by simple operation. SOLUTION: This pachinko island base 1 is provided with an inclination angle adjusting device 8 to simultaneously change axial inclination angles of a plurality of pachinko bases 6, so the inclination angle of the pachinko bases 6 can be simultaneously changed by one-time operation without performing adjustment of the inclination angle for each pachinko base 6. A winning ratio of the pachinko bases 6 can thus be easily adjusted.
