Complete guide
German Clock is a complete browser implementation with its own versioned rules profile. Deal a single waste into thirteen rank piles whose four horizontal layers share suit and alternate color vertically.
All fifty-two cards begin in stock, the waste is empty, and thirteen empty foundation piles represent ranks Ace through King.
Draw stock cards singly to waste. A waste card enters only the pile matching its rank, with at most four cards per pile. The first card placed at a depth fixes that entire layer's suit across all thirteen ranks, while successive cards within each rank pile must alternate color. One waste redeal is available.
Fill all thirteen rank piles to four cards, producing four complete same-suit layers with alternating colors between depths. On the final pass, follow the fixed layer suit as a queue and place every matching rank immediately before another waste card covers it.
Choose each new layer's suit only when many matching waste cards are reachable, and track the required opposite color above every partially filled rank pile. A card with the correct rank can still be illegal when its suit differs from the layer or its color matches the prior card in that rank pile.
