Microsoft Jewel is a match-three in the Bejeweled tradition: swap adjacent gems to line up three or more, clear them, and let what falls from above create new matches.
It's the format at its cleanest — no story, no stamina system, just a board and the cascades you can set up on it.
Cascades. Matching low on the board makes everything above fall into fresh matches automatically, which scores far more than an isolated three.
Yes — same swap-and-match-three format that Bejeweled popularised.
Yes — swipe to swap gems. Nothing to install.
