Super Mario 63

Super Mario 63 is a remarkable fan-made browser game that recreates the magic of Super Mario 64 entirely in Flash — now playable via modern emulation. Created by Runouw, this passion project faithfully reimagines Nintendo's iconic 3D platformer as a 2D adventure packed with FLUDD mechanics, 64 Shine Sprites to collect, and expansive worlds that rival the original in ambition and scope.

To play, use arrow keys to move and jump, with additional controls for the FLUDD water pack that lets Mario hover, dash, and rocket across levels. The game features a full overworld hub, multiple distinct stages, and secret areas that reward thorough exploration. Collecting Shine Sprites unlocks new levels, while hidden Star Coins add extra replay value for completionists.

Super Mario 63 is addictive because it nails the satisfying momentum of classic Mario movement while adding its own creative twists. Mastering FLUDD combos to reach hidden platforms, hunting down every last Shine Sprite, and discovering secret rooms keeps players coming back for hours. Speedrunners have also built an active community around optimizing routes through the game's generous level design.
