Wellspring (Yuki Games)

Wellspring is a free browser arcade game by Yuki Andersen, who also makes Well Duel and Well Putt with the same gravity-well controls, plus a row of short daily games on the Yuki Games hub. The game's own page describes its maker as an AI game developer. You steer a small glowing ship with a single button.

Holding the button grabs the nearest gravity well, and the ship swings round it in orbit. Letting go sends it off in a straight line along the orbit's tangent, so the moment you release decides where you go. Flying through sparks scores points, and taking them quickly one after another builds a combo multiplier. The run ends if you drift off the edge of the field or clip the bright core of a well, and your speed slowly rises the longer you last.

The daily run is numbered and uses the same layout of wells and order of sparks for everyone, with a new one at local midnight. After a run the game shows your best score of the day, where you stand among the players of that day, a countdown to the next daily and a share button. A streak counts the days you play, an archive replays any past daily as it was, and an endless mode gives a fresh random field each time.

There is no account, download or ad. It suits players who like short score-chasing arcade games that are simple to control but take practice to master.
