Reveal useful information

Here is what to know. A longer visible run is not automatically better than a move that opens the tableau. Compare possible moves by what they uncover as well as by the length of the sequence they create. A move that reveals a hidden card gives you another fact to work with. You cannot know the identity of a hidden card before it is exposed.

Value an empty column

Here is what to know. Consider the next destination before filling your only empty column. You must eventually fill every empty column before dealing from the stock. An empty column can hold a temporary sequence while you rearrange other cards. A whole-column move into another empty column does not reveal anything new on its own.

Favor matching suits

The key details are straightforward. Same-suit descending cards remain movable as a group. Matching colors alone do not give that benefit in four-suit Spider. Look for ways to join matching segments without burying a card you need elsewhere. A shorter matching group can be easier to reuse than a longer mixed-suit build.

Use mixed builds deliberately

Before extending the mixed build, look for temporary destinations that could help you separate it. Avoid assuming that every descending column can be moved as one unit. A mixed-suit move can be worthwhile when it reveals a card or frees a column. Only the same-suit descending segment at the bottom moves together.

Know the limited destination

On this website, the following points apply. Placing a King in your last empty column may reduce your immediate rearrangement options. A group beginning with a King has the same limitation. Moving a King can still be useful when it uncovers an important hidden card. A King requires an empty column because there is no higher rank.

Pause before dealing

Keeping all columns occupied is a requirement for using the stock. Check whether a visible move can expose a card or join matching suits before you deal. A stock deal adds one card to every column and may disrupt useful sequences. Dealing remains an option when the visible layout offers no useful improvement.

Compare follow-up choices

Keep these details in mind. No simple rule can guarantee success on every randomly shuffled deal. Ask what a move will let you do next rather than considering only the first destination. Try to leave more than one useful destination when the layout allows it. Moving a small segment may release a second move that was previously blocked.

Use undo as a lesson

The timer does not move backward when you undo. Compare what each alternative reveals instead of repeating the same sequence without a new idea. Replay is useful when you want to revisit the opening arrangement of the same deal. Undo restores the previous card state, including flips and collected runs.

Make the final decision

Repeatedly using Hint cycles through the available suggestions for the current position. A hint does not reveal the stock or hidden tableau cards. Hints search legal moves in the visible position. The suggested move may be useful for investigation without leading to a win.

Choose a comfortable challenge

Here is what to know. Two suits introduces the difference between a descending build and a movable same-suit group. One suit is useful for practicing rank order and the controls. Four suits gives you more suit conflicts to resolve using the same rules. A short, focused session can be more useful for learning than rushing to finish a difficult deal.
