Hollow Golf
Sep 27, 2026 — Mini golf on the inside of a hollow world, where gravity pulls outward and every fairway curves up.
Hollow Golf takes the world from Hollow Light and puts a mini golf course on the inside of it. Gravity pulls out, toward the ground under your feet, so every fairway curves up into the sky, the Sun hangs in the middle, and the far side of the course is over your head. Nine holes across four themed worlds: a garden, a glacier, rooftops, and floating islands around a crystal star core. The last hole's green is on the other side of the world, and the only way there is over the Sun.
Drag back from the ball to aim and shoot; putter, wedge and a "sky driver" that lofts the ball across the middle of the world. It's three.js with a fixed-step 240 Hz physics sim on the sphere, so shots are deterministic. The promo below uses real shots found by a search script, including the hole-in-one on hole 9, rendered frame by frame from the game's own engine.
