Abstract
A portable modular outdoor playing arena having a plurality of modular floor panels and a plurality of generally vertically oriented modular side panels. The floor panels have a generally smooth flat upper surface and side surfaces that depend therefrom at approximate right angles. The floor panels are adjoined in a closed polygonal configuration to create a playing surface. The side panels surround and abut the floor panels and exert a compressive force on the floor panels to prevent lateral separation of adjacent floor panels. A seal forms a fluid tight connection between adjacent floor panels and at the juncture of the floor panels and the side panels. Each of the floor panels include adjustable legs to support the floor panels on the ground or on a sub-surface. The legs are vertically adjustable to allow for the levelling of the floor panels so that adjacent floor panels can be individually levelled and supported to provide a level playing surface.
