The Grand Slam - The Complete Down the Line Collection
5 July 2026
Down the Line started as one d20 tennis game. A season later it's a full set of Majors: the clay of Roland Garros, the grass of Wimbledon, an offline tournament app that runs any event on any surface. Enough that buying it piece by piece had started to feel like hard work.
So here's the shortcut. The Grand Slam is the complete collection in a single download.
Everything's in it:
- The core engine - Down the Line, the d20 game itself, with all-time-great ratings, custom player creation, a blank scoresheet and a 32-player bracket
- Roland Garros 2026 - the full 128 draw, every R1 pairing from the real draw, clay-court serve rules, three resolution speeds, eight print-ready PDFs
- Wimbledon 2026 - both the Gentlemen's and Ladies' singles, all 256 players rated, grass-court rules where the serve is king, and the full offline tournament app with four play modes and a build-your-own engine for any tournament on any surface
It's the cheapest way into the full range, and everything you need for the whole 2026 Slam season. If you already own a pack or two, the bundle fills the gaps in one click. If you're new to Down the Line, start here - the core engine is all you need to play, and both Majors are already in the box.
The complete game, from first serve to championship point. Print it, rate it, roll it.
