Four players, two teams. Each team pairs its two scores into a single two-digit number — lowest score leads. The gap between the numbers is the hole.

Both partners hole out. The lower score becomes the first digit: a 4 and a 5 makes 45 — not nine.
The other team builds its own number the same way. The difference between the two is what the hole is worth.
Under most house rules a birdie — or a blow-up — reverses the opposition number. 45 becomes 54, and a two-point hole is suddenly a nine-point hole.
Vegas lives or dies on whether everyone can see the number. Still You shows both team digits on every hole and animates the reversal the moment a flip triggers, so nobody is recalculating on the next tee.
Every one of these is a setting in Vegas — set once for the group and reused every round.
Off, birdie flips, or birdie and eagle. Whose number reverses is up to your group.
Standard lowest-first, or the house variant where a blow-up forces the high score forward.
Points per unit or a currency value per unit — set once for the group.
Fixed for the round, drawn at random, or rotated every six holes.
The most volatile game in the app, and the reason most groups never go back to plain strokeplay.

Beta groups get all six modes from day one. Four to a group — bring your regulars.
