Only Up: Gravity Parkour 3D is a three-dimensional sports game that shares similarities with Only Up Parkour and Only Up 3D Parkour: Go Ascend. The player directs an avatar dressed in motorcycle gear to climb as high as possible into the air. The game starts in an industrial zone where the player directs the character to jump on a car and then a large rusted pipe.
The player can direct the guy to walk, run, jump and even climb objects that he comes across during the ascent. Objects include buildings and other structures, metal storage containers, motor vehicles, small and large concrete and metal pipes, traffic signs, and wooden ladders and pallets. They might direct the avatar to climb a structure or leap across roofs or signs. The player must have fantastic hand-eye coordination to make certain that the character doesn't fall off one of these objects.
Only Up: Gravity Parkour 3D allows the player to save their progress at checkpoints marked with red flags. The player can also earn money to pay for different colors of gear. If they watch an advertisement, they earn 200 coins.
