What you are trying to do
Your main goal is to move every card into four foundation piles, one per suit. Foundations are built by suit, but Osmosis adds a twist: you may only place a card of a particular rank on a foundation after that same rank has already appeared in the foundation above it. This creates a slow, careful unlocking of cards — like water seeping through layers, which is where the name comes from.
What you need and how to set up
You need one full, normal 52-card deck. Shuffle well. Because rule sets and table layouts vary between sources, the exact deal and tableau can differ. A safe beginner setup is to lay out the four foundation areas and deal a small tableau or reserve of face-up or face-down cards from which you will try to free playable cards. Check the authoritative rules for the precise setup your group prefers.
How to play
- Decide which published setup you will follow (official sources differ). The core idea stays the same across versions.
- Expose cards from the stock or tableau according to your chosen setup. Some versions use a stock and waste, others use a face-up grid or reserve.
- When a card can legally go to a foundation, move it there. Remember: foundations are by suit, and you can place a card of a given rank only after that rank has already appeared in the foundation above it.
- If a card cannot yet go to a foundation, leave it in the tableau, waste, or reserve. Play continues as you expose more cards and create new possibilities.
- Use any allowed rearrangements (moving single cards or small groups) that your chosen rule set permits to free cards. Exact movement rules vary by source, so follow the version you chose.
- Repeat exposing and moving until you either place all cards on foundations or you have no legal moves left.
How a round or game ends
You win if all 52 cards end up in the four suit foundations following the rank-unlocking rule. The game ends in a loss (or a stop) when no further legal moves are possible under the rules you've chosen. Because several details are version-dependent, check the authoritative rule reference for any special redeal, pass, or winning exceptions.
Beginner tips
- Play slowly and look for moves that will reveal or free other cards.
- Prioritize placing ranks that unlock many others, rather than just the first legal move you see.
- Keep suits organized in your head. Because foundations are suit-based, a single blocked suit can stop progress.
- If your version allows redeals or passes through the stock, use them strategically to expose ranks you need.
- Always confirm the exact move and setup rules before you start; small differences change good strategy.
FAQ
What deck do I use?
Use a standard 52-card deck. Osmosis uses a normal full deck — no special or purchased deck is required.
Can I move sequences or only single cards?
That depends on the version. Some rule sets allow limited sequence moves, others only single cards. Check the authoritative rules for the exact movement permissions for the version you are playing.
Is Osmosis just for one player?
Yes. Osmosis is a solitaire (single-player) patience game. It’s great for focusing and planning moves.
