Flush nine hidden cards, the blind mice, out of three columns in this Scorpion variant, then build strict same-suit runs toward a skill-driven 40% win rate.

Three Blind Mice Solitaire is a Scorpion variant that takes its name from the nursery rhyme: three of its ten columns start with three face-down cards at their base, and those nine hidden cards are the blind mice you must flush out to win. The other seven columns are dealt entirely face-up, and the two cards left over after the deal sit beside the tableau as a small reserve.
Like Scorpion and Yukon, the game lets you pick up any face-up card and move it with everything piled on top, no matter how jumbled the stack. Building, however, is strict: a card may only be placed on the next-higher card of its own suit, empty columns accept only Kings, and nothing leaves the tableau until a full King-to-Ace suit is assembled. That strict same-suit building rule is what keeps this rated medium difficulty; expect to win somewhere around 40% of the time. It's played with a single deck, and skill counts for more than luck here.
Scorpion Solitaire and Double Scorpion Solitaire sit in the same family, both built on that same pick-up-any-stack rule.
Three Blind Mice fans should give Spider Solitaire a spin too.

4 foundation piles: Each one receives a complete sequence of thirteen cards of the same suit, from King down to Ace.
10 tableau piles: Build down in suit. Any face-up card can be moved along with all the cards on top of it. Only Kings may fill empty spaces. Each pile is dealt 5 cards; in the first three piles, three cards are face-down and two are face-up, while the other seven piles are entirely face-up.
Reserve: The two cards left over after the deal lie here face-up. The top card is available for play.
There are four foundation piles.
Single cards are never allowed to be moved to the foundation. Only once you've built a complete sequence on the tableau, thirteen cards of one suit in order from King down to Ace, can you transfer it to a foundation pile.
The top card of each foundation can be moved back into play if another pile will accept it.
The reserve holds the two cards left over after the deal, both face-up.
There is no stock to deal from, and no cards may be moved into the reserve. The top card of the reserve may be played to any tableau pile where it fits.
Ten tableau piles hold five cards each. In the first three piles the bottom three cards are dealt face-down; every other card is dealt face-up.
A card can be added to a tableau pile only if it's one rank lower and the same suit as the pile's current top card, so the only card that fits on an 8 of spades is a 7 of spades.
Any face-up card in the tableau may be moved to another pile where it fits, bringing all cards on top of it along with it, regardless of their order. Face-down cards turn over as soon as they are uncovered.
Only Kings, or groups of cards led by a King, may fill empty spots in the tableau.
