01Fill every cell with a ♥ or a ♠.

02Each row and column must contain exactly three of each suit.

03No more than two of the same suit may appear consecutively in any direction.

04= means the two cells share the same suit. × means they differ.

05Tap once for ♥, again for ♠, again to clear. Pre-set cells (darker) are fixed.

06Each hand has exactly one valid solution. Logic, not guesswork.
