One real course, nine holes, the same wind for everyone.
Sweden’s 50 and the world’s 100 highest-rated courses on UDisc, rebuilt from their real hole positions, terrain and woods. Practice rounds get their own wind and don’t touch the leaderboard.
Up to four players on one phone. Everyone tees off in order of honours, then whoever lies farthest from the basket throws next. Hand the phone over when your name shows up.
Discs wear in: trunks, stones and roots beat them in (●), which makes them turn more and fade less. Swap in a new one with New. Pick up to 8 discs, including at least one putter. Flight numbers are speed | glide | turn | fade as published by the maker. Charts show a flat, full-power right-hand backhand in calm air.
Each tree has a crown that depends on its species and height. Trunks always stop the disc. Inside a crown the disc may clip branches: the denser the crown and the deeper the disc goes in, the likelier the hit. Orange on the preview shows where your line brushes branches, with the chance of getting through.
Where the disc stops depends on how it lands. Flat landings skid; a disc that lands leaning over on its edge can turn into a roller that curls toward its lean and follows the slope; some land dead in soft ground or stick into an uphill bank, and a hard flat landing on the fairway can skip a long way. Sticks, stones and roots lie on the ground (most in the woods, see the map up close) and can kick the disc sideways or stop it. A disc that hits a tree may drop, kick on toward the basket or kick back. A word pops up on the map when something like that happens. It is all seeded by your throw, so the same throw always ends the same way and everyone gets a fair daily round.
About one day in five it rains: wet ground stops skids and rollers sooner and grabs more discs, short wet grass can make a disc hydroplane, and a slippery grip narrows the release and putting zones. On the closing holes of a round under par the needles shake with nerves (and on the one-throw closest to the pin). Trunks, stones and roots beat discs in (the dots on a disc): a worn disc turns more and fades less, and you can swap in a new one in your bag. A disc that ends deep in the woods or the reeds can be lost: one penalty throw from where it disappeared, and that disc is gone for the rest of the round (never your last one). Half the discs that land in water sink.
The daily round is a random course from Sweden’s top 50 and the world’s top 100; every course comes up once before any repeats. On bag days (about one in five) you play it with three discs of your choice. Putting · JYLY: ten sets of five putts, starting at 10 m; a set scores makes × metres and the next set is putted from 5 m + makes (max 500). Closest to the pin: one tee shot on a par 3 picked for the day, measured to the pole. The first game of each kind per day goes on the leaderboard, which also shows the month (best average against par over at least ten ranked rounds; last month’s champion gets a line on the home page) and the ace wall with every ace: date, course, hole and disc. After a throw you can watch it again with Replay; aces and long putts finish in slow motion. On phones that support it, the game vibrates on release, tree hits and chains.
Pick Pro or Noob on the home page. In Noob every meter moves at half speed. Today’s ranked round keeps the mode it started with, and Noob scores carry a badge on the leaderboard (filter All, Pro or Noob).
Holes go up and down. The tag next to the hole name shows how far the basket sits above or below you, the map has contour lines (one metre apart, thicker every five), and the side view cuts through the ground. It only opens when you ask for it: tap Side view on the map (or press V) to see the hole profile or your line with the disc’s height and the trees beside it, and tap again to close it. Uphill throws land short, downhill throws carry further and roll on, and the aim tick already allows for it. Putting uphill comes up short; downhill misses run long.
The courses are Sweden’s 50 and the world’s 100 top-rated courses on UDisc (the 2026 lists), nine holes at a time, using each course’s most-played layout. Tee and basket positions, doglegs, pars and lengths come from UDisc (a few pars from short-tee layouts are evened out, e.g. a 60 m par 4 plays as a par 3); woods, roads, paths and creeks from OpenStreetMap; heights from AWS Terrain Tiles. On Ale DGC White the OB lines, hazards and drop zones are traced from the official tee signs; elsewhere roads, water and built-up areas act as OB, so a course’s own local rules may differ. Woods come from ESA WorldCover 2021, a satellite land-cover map with 10 m cells: trees stand where the satellite sees tree cover, and fairway widths follow the open lanes it sees. Individual trees inside the woods are placed by the game. Individual trees are placed by the game to match the woods, so treat the details as a close likeness, not a survey. Disc names and flight numbers come from the manufacturers; the flight model is a game approximation, not a physics simulation.
Today everyone plays the daily round with only three discs. Pick them from your bag; they are locked in for the round.
