28-0: Tennis Draft Slam

About this app

No player has ever won all four Grand Slams in a single year in the Open Era. Build the one who could. 28-0 is a free tennis draft game where you construct the ultimate player from 3,626 real ATP seasons spanning 1991 to 2023. Pick six attributes — Serve, Forehand, Backhand, Return Game, Movement, and Mental — each pulled from a different real player-season. Then run your creation through all four Grand Slams, seven rounds each, 28 matches total. Win them all and you've pulled off the Calendar Slam. HOW IT WORKS Spin the reel to draw a random ATP season. Sometimes you get a choice between two. Lock in the one that fits your build, or keep spinning and see what comes up. Every attribute slot is filled by a different player-season, so there are no shortcuts — your Dream Player is built piece by piece. The pool covers the full modern era of ATP tennis. You might land Djokovic's 2023 return game, Nadal's 2008 clay movement, or Sampras's 1994 serve. The combinations are effectively endless. BUILD SMARTER WITH SYNERGIES Draft two attributes from the same player and you unlock a Synergy bonus that boosts your overall rating. Seven Synergies are available: - WEAPON STACK — Double down on one player's strengths - CLAY KING — Dominate on red dirt - COUNTER-PUNCHER — Make opponents beat themselves - CLUTCH SERVE — Holds and aces when it matters most - THE WALL — An impenetrable defensive baseline game - IRON LEGS — Outlast everyone in five-set battles - GRASS MASTER — Built for the fast courts of Wimbledon Synergies aren't guaranteed — they're earned by drafting smart and getting lucky at the right moment. SIMULATION BUILT ON REAL DATA Your player doesn't just face generic opponents. The simulation draws on real surface win rates from ATP historical data. Clay specialists struggle on grass. Serve-and-volley builds thrive at Wimbledon. The stats your Dream Player carries into each Slam are the actual stats from the seasons you drafted — so your choices genuinely matter. Each Grand Slam runs seven rounds. Survive the draw, protect the ranking points, and advance. All four Slams. All 28 matches. RANKING FILTERS Filter your draw pool by ranking tier — All, Top 100, Top 50, or Top 10 — to tighten up your odds and build with intention. NO ACCOUNT. Your personal best is saved on-device. Just the draft and the simulation. THE CHALLENGE The Calendar Slam has never been achieved in the Open Era. Not by Djokovic. Not by Federer. Not by Nadal. The closest anyone came was Djokovic in 2021, who won the first three before falling at the US Open. Your Dream Player has stats that no real player ever had. That's the point. The question is whether you can put them together in the right combination, survive four Slams worth of variance, and go 28-0. Most people don't make it on the first try. Or the tenth. Build your player. Run the simulation. Go 28-0.
