Replaying the same Solitaire deal is useful when you are testing one decision. It is less useful when you repeat the same moves until you remember the answer. A good replay ends with a rule you can apply to a new layout, such as checking the Queen a King will receive before filling a column.
Undo and replay also change the information available to you. Once you have seen a hidden card, you cannot make yourself unaware of it. That is fine for practice; simply keep a replayed success separate from a first-attempt result.
Pick one point where you have two choices
Choose a position with two plausible legal moves. Write down the visible reason for each before exploring either branch. “This uncovers a card” is better than “this feels right,” because you can compare the prediction with the result.
For example, an empty column can take either a black King from the waste or a red King-led run from the tableau. The red run exposes a hidden card when it leaves; the black King could receive an already accessible red Queen. Both moves have a purpose. Your exercise is to discover their consequences, not to assume that the same color is always best.
Use a small decision log
| Stage | What to record |
|---|---|
| Before moving | The two choices and the benefit you expect |
| After the first choice | The card exposed or the sequence made accessible |
| After Undo and the alternative | What changed, including any new obstruction |
| On a fresh deal | Whether the same decision rule helped identify a move |
Do not judge the first move only by whether that attempt eventually wins. A later mistake may spoil a strong opening, while a weak opening may survive a forgiving layout. Describe the local effect you can actually observe.
Rewind far enough to compare fairly
PlaySolitaire supports undo through the current game’s move history. If your first branch required several actions, reverse those actions until the comparison position is restored. The cards, stock/waste state and available column must match before you try the other choice.
The strategy guide’s fixed practice board is particularly useful: its Restart control returns to the same teaching deal. Use that board when you want a repeatable starting point rather than assuming that opening a new game will reproduce your current layout.
To transfer the lesson, play Solitaire online and practice the decision in a fresh game. This final step checks whether you learned to inspect a position or merely remembered one sequence.
Separate three kinds of success
A first-attempt win uses the information encountered during that attempt. An undo-assisted win may compare branches and reuse revealed information. A replayed win benefits from knowledge retained from earlier attempts. All can be enjoyable, but they answer different questions about your play.
Our published methodology includes unlimited undo in its observed completion rates; it does not describe those results as unaided first-try performance. If you keep your own notebook, choose a convention and keep it consistent.
Know when to stop the exercise
Stop after you can state what the experiment taught you. You do not need to solve the whole deal. If both branches remain unclear, “no conclusion yet” is an honest result. A stuck-position check can help distinguish a missed legal move from a longer-term planning problem.
The useful takeaway is specific: “I filled the only column before checking an available Queen,” or “the foundation move removed my only landing card.” That gives your next game a concrete question to ask.
