[DEMO] System98 - Spider Solitaire

Only 5 game modes available in the DEMO.

31 variants of spider — Scorpion, Tarantula, Wasp, Beetle, Spiderette, Mondo Spider and the rest — sit behind a grey-and-teal desktop with draggable icons, a Start menu, a taskbar and real movable windows.

• 78 achievements, tracked locally — no account, no launcher, no telemetry
• A jazz soundtrack that shifts intensity as a game tightens up
• Ten languages, with full rule sheets in each
• Saves your game mid-hand and picks it back up next launch
