An Ulterium game for iPhone

Sweep Ball Duo

Head-to-Head Arcade Roller

The arcade alley game built for iPhone Duo — open it up and play two players, head to head on side-by-side alleys. Pull back, let go, sink the 50s and win a ribbon of tickets.

Coming soon to the App Store

No ads. No accounts. No data collected. Just roll.

Two-player match on an opened iPhone Duo — side-by-side alleys with separate scores
End of a head-to-head match — Player 2 wins and both ticket strips feed out
Tickets paying out arcade style — a perforated strip folding into a pile

Two players. One iPhone Duo.

Open it partway like a laptop — both lanes on the bottom screen, both targets standing up on the top, just like a real cabinet — or lay it flat for two full-length alleys side by side. Each player gets their own score, streak and HOT cup, racing the same clock. Fold it shut mid-match and the game pauses until you open it again.

The arcade, in your hands

Pull the ball back and let go — or just flick it up the lane. Every ball is a lit, spinning wooden ball; every cup is a real hollow you can watch it drop into; every throw sounds like the real thing. Tilt your phone and the whole cabinet shifts in true 3D, with rich haptics for every pull, roll, bounce and score.

Tickets!

Every match pays out the arcade way: a long perforated strip feeds out of the slot and folds into a pile on the floor. Land 30 or more in a row to build a multiplier up to ×4, chase the double-paying HOT cup, and earn bronze, silver, gold and diamond medals.

On any iPhone

Play solo on any iPhone running iOS 17 or later — pick a Short, Medium or Long match, each with its own best score, and let the 40s and 50s add time to the clock. On iPhone Duo, play solo on the cover screen or open it up for the full two-player arcade.
