Tri Towers Classic Solitaire

Tri Towers Classic Solitaire sets its table in front of a blue-turreted castle at night, with rose beds lining the path and a grey-haired noblewoman in red to explain the rules.

She gives them plainly. Discard every card on the board. A card can be taken if its value is one rank higher or lower than the card on the deck. When nothing fits, turn the next card from the deck and try again.

Three pyramids of face-down cards sit above a row of nine face-up ones, and anything legal is ringed in bright green, so the puzzle is choosing which legal card to take, not spotting it.

A second card lists the scoring. Finish quickly for extra points, build long streaks because the longer the chain, the more it pays, collect spark power-ups, and watch the round pass figure that tells you what it takes to win. Taking one queen set the streak to one and put five hundred on the scoreboard.
