King and pawn against king: promote in 6 against a perfect defence. Tap a piece, tap where it goes. Only one first move keeps the win, and there is no take-back.
Queen is a free daily chess endgame from Mind Loft. Every position is a king and one pawn against a bare king, with a proven win: walk the pawn to the eighth rank and promote it, safely, against a defence that never makes a mistake. Tap a piece and its legal squares light up, so no chess notation is needed.
The win fits the stated number of moves exactly, verified by two independent solvers, and exactly one first move keeps it. This is the endgame every chess player is told to learn first, the opposition, spare tempi, the square of the pawn, and the game plays it out honestly: a promotion the defending king can capture straight back, or one that delivers stalemate, is a draw, exactly as it is over the board.
A new position drops every day at midnight Eastern, the budget deepens through the week, and the Sunday Edition is the longest walk of all, a win in twelve.
