How to play Osmosis Solitaire

Four reserve piles of four cards are dealt face up, and only the top card of each can play. One card starts the top foundation row. The other 35 cards form the stock.

The top row takes any card of its suit, in any order. Each lower row opens with a card of the same rank as the top row's first card, and that card sets the row's suit.

After that, a lower row accepts cards of its suit only if the same rank is already in the row directly above. Play cards from the reserves or the waste. Get all 52 cards into the rows to win.

Osmosis rules: stock and redeals

Tap the stock to turn one card at a time onto the waste. When the stock runs out, redeal the waste as many times as you like. Rows open from the top down, so the second row must start before the third.

Because ranks seep down row by row, a card can be stuck in the stock until its rank reaches the row above.

Osmosis Solitaire tips

• Fill the top row as fast as you can. Every rank it holds opens that rank for the row below.
• Watch for the base rank. You need one in each suit to start all four rows.
• Play reserve cards whenever possible. Emptying a reserve pile uncovers the cards beneath.
• If nothing can be played, keep cycling the stock: new ranks may have opened since your last pass.
• Hint points out playable cards when you're stuck.
