Only Up Balls throws you into a vertical sprint where gravity calls the shots and you keep breaking its rules. Guide a hefty ball across rails and platforms, hopping track to track, climbing toward the glowing portal without kissing the void. Physics is your frenemy, timing your best weapon. It starts light in the Noob tier so you can lock in the basics. Then the tempo spikes: Pro sharpens your reflexes, Hacker demands precision, and Extreme punishes the slightest slip. Every jump matters. Every landing snaps. Challenging, vertiginous tracks keep piling up while you weave past traps, knock rivals aside, and blast nasty little robots off your route. Run solo for pure focus, or flip to 2‑player and race a friend for bragging rights. You'll scoop up coins and gems to unlock fresh skins, cool hats, and flashy trail effects, so the ball feels uniquely yours. Chasing 3‑star finishes on every stage turns each attempt into a record hunt, and that final portal? It's always calling. Customization, retries, shaving seconds the loop is addicting, and the climb never stops, even when your sweating at 200 meters. Hit Play and climb to the portal at the top!
