Same board, race your friend's ghost.
Pairshade is a mahjong solitaire (tile-matching) game. Every day there is one board that is the same for everyone in the world. When you clear it, your moves are recorded, and you can send a link that says "beat me on this board."
Each day brings a new board, identical worldwide, and every board can be solved.
Open a friend's link and their tiles fade away in real time, translucent, while you solve the same board. At the end, time and moves are compared side by side.
A link contains only the board, the moves, and an optional display name. No account registration is required.
Hints, shuffles, and undo can be used with jade (in-game currency) or by watching a rewarded ad. Premium removes ads and unlocks past boards and unlimited hints.
