531 Golf

5-3-1 (also known as Nines) turns every hole into a contest. On each hole, nine points are shared between three players based on how they finish — creating constant momentum shifts where no one is ever out of it (think of it as matchplay for 3-ball!)

Now with Split Sixes mode, giving you another classic 3-ball format to keep your rounds fresh.

But once the rivalry kicks in, keeping track of points, ties, stroke indexes and shot allocation can quickly pull attention away from the golf.

The 531 Golf app handles all of it. -Every hole calculated correctly -Ties resolved instantly -Stroke indexes applied automatically -Results, golfer stats and leaderboards updated

And if you want to add an edge, switch on: Birdie Bandit and Eagle Assassin mode (or 2 shot sweep for Split Sixes)

Optional bonus gameplay that rewards the only birdie or eagle on a hole — or a win by two shots in Split Sixes — and adds an extra spark to the round.

So every hole is settled cleanly, the banter stays "friendly", and the competition lasts all the way to the 18th green.

If you ever play in a 3-ball, this is the app you want in your pocket.
