Here’s the structure, and it’s nasty in the best way. OSS XL runs from March 1st to March 23rd with 50.000.000 $ guaranteed across the series, and it peaks with three Big Main Events carrying 5.000.000 $ in combined guarantees. Day 1A fires on Sunday, March 15th, Day 1B on Sunday, March 22nd, and everyone who survives comes back for Day 2 on Monday, March 23rd — with buy-ins set at 2.650 $ (2.000.000 $ GTD), 1.050 $ (2.000.000 $ GTD), and 215 $ (1.000.000 $ GTD). Alongside that, ACR drops a Monster-style Regular Multi-Flight with 1.500.000 $ GTD for 630 $ where Day 1 flights run all the way through March 23rd, then Day 2 lands on March 23rd and the final table plays out on March 24th — meaning you’ve got repeat shots to bag a stack instead of praying for one perfect schedule window.
And if you live for volatility, the series leans hard into Mystery Bounty multi-flights: three separate 500.000 $ GTD Mystery Bounty blocks at 109 $ buy-in across March 2–8, March 8–15, and March 15–23, plus lower buy-in Mystery Bounty options at 33 $ (150.000 $ GTD) and 5.50 $ (100.000 $ GTD). That’s before you even talk about the “headline spice” like Phil’s Thrill XXL — a 10.300 $ beast with a 95 $ satellite route — because OSS XL loves giving shot-takers a ladder instead of a brick wall.

Now the part grinders should circle in red: the 65.000 $ OSS XL Leaderboard Competition is 100% funded by ACR, and it runs the full March 1–23 stretch. There are three divisions so you’re not forced to battle only nosebleeds for leaderboard money: High (104.50 $+), Medium (16.50 $ to 88 $), and Low (under 15 $). First place pays 15.000 $ in High, 7.500 $ in Medium, and 4.000 $ in Low — and the points formula rewards performance in bigger prize pools while still valuing finishes (Square Root(prize pool) / Square Root(finishing place)), with points awarded to in-the-money players only and only in series events. Translation: you don’t need to win once — you need to show up, cash, and keep showing up, and the leaderboard quietly turns your “pretty good run” into extra money on top.

Why this event is such a registration magnet is simple: OSS XL gives you multiple ways to win without changing your identity as a player. If you’re a tournament sniper, you take clean shots at the three Main Events and the 1.500.000 $ multi-flight while avoiding the “one bullet, one dream” trap. If you’re a volume grinder, you farm the Mystery Bounty blocks and turn every deep run into a double-sweat: payout + leaderboard points, with the upside that a single bounty pull can instantly reframe your whole night.
And if you’re a low-stakes player who usually gets ignored by big series, the Low leaderboard lane is literally designed to make your consistency matter — you’re not just cannon fodder for the top regs, you’re competing in your own race. OSS XL is built for players who want options — multi-flights for repeat shots, mystery bounties for ceiling, and a leaderboard that pays the people who keep going. If you’re playing in March, play where the guarantees are oversized and the extra money is baked in!
