TinySol, a compact and compatible Klondike Solitaire game for DOS, has released version 1.3. It runs on vintage hardware and emulators, supporting various video modes and input options. Its release highlights ongoing interest in retro computing and small software projects.
TinySol, a tiny Klondike Solitaire game for DOS systems, has been officially released in its latest version 1.3, supporting a wide range of hardware and video modes. This development is notable for vintage computing enthusiasts and those interested in small, efficient DOS games, as it demonstrates ongoing activity in preserving and enhancing classic software for modern and legacy systems.
Developed in x86 Assembly and first released in early 2022, TinySol is a free, 3KB game designed for good playability on vintage computers, including monochrome and color systems. The latest version, 1.3, released on May 25, 2026,, includes fixes, performance improvements, and new features such as multiple build options (full, medium, tiny, micro). It supports various hardware configurations, including 8088, 286, and Pentium systems, and runs on MS-DOS 3.30 through 6.22, as well as DOS emulators like DosBox.
The game features support for multiple video modes—CGA, AT&T 6300, EGA, and VGA—detecting modes automatically or switching on the fly with function keys F1-F4. It offers both keyboard and mouse controls, with mouse support for select modes, and includes features like save/load game state, auto-finish, and score tracking. It has been demonstrated on hardware such as Zenith Heath/Z-110 and a 286 running FreeDOS, with positive performance reports from users.

Runs on (almost) anything with a DOS prompt
TinySol was engineered for reach: one tiny binary that adapts to four decades of PC hardware, real or emulated, monochrome or color.
8088 → Pentium
From the original IBM PC’s 8088 through 286 up to Pentium-class CPUs — the same binary plays across the whole line.
MS-DOS 3.30 – 6.22
Runs on MS-DOS 3.30 through 6.22, plus community favorites like FreeDOS — no extensions, no drivers, no fuss.
DosBox & friends
Equally at home inside DOS emulators like DosBox, so modern machines can deal the cards without vintage silicon.
CGA · EGA · VGA · AT&T
Four graphics modes, auto-detected at launch or switched on the fly with function keys F1–F4.
Keyboard + mouse
Full keyboard control everywhere, with mouse support on select modes — select piles, auto-send cards to foundations.
Proven on real metal
Demonstrated on a Zenith Heath/Z-110 and a 286 running FreeDOS, with positive performance reports from users.
Auto-detected at startup · switchable live via F1–F4 · monochrome & color systems supported
One 3KB binary · the entire IBM PC hardware line
Four builds, one deck of cards
Version 1.3 lands with fixes, performance improvements, and a new multi-build system — pick the binary that fits your machine, from full-featured down to micro.
