Hoyle’s Official Book of Games: Volume 2 (1990) is a DOS-based solitaire compilation by Sierra On‑Line. Unlike its predecessor, this volume offers 28 single-player solitaire variants—including Klondike, Spiderette, Pyramid, and Baker’s Dozen—each with Easy and Hard modes . With a 320×200, 16-color VGA display and top-down interface powered by the SCI engine, it includes shuffling animations, complete rule summaries, and replay options.
