A guide to your next move.
Look under the visible cards
A move that reveals a hidden card gives you another fact to work with. 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. You cannot know the identity of a hidden card before it is exposed.
Value an empty column
An empty column can hold a temporary sequence while you rearrange other cards. You must eventually fill every empty column before dealing from the stock. Consider the next destination before filling your only empty column. A whole-column move into another empty column does not reveal anything new on its own.
Make groups that can move
Here is what to know. A shorter matching group can be easier to reuse than a longer mixed-suit build. 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. Same-suit descending cards remain movable as a group.
Use mixed builds deliberately
On this website, the following points apply. Only the same-suit descending segment at the bottom moves together. A mixed-suit move can be worthwhile when it reveals a card or frees a column. Avoid assuming that every descending column can be moved as one unit. Before extending the mixed build, look for temporary destinations that could help you separate it.
Plan around Kings
The key details are straightforward. 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. A group beginning with a King has the same limitation. Placing a King in your last empty column may reduce your immediate rearrangement options.
Review the tableau first
Keep these details in mind. A stock deal adds one card to every column and may disrupt useful sequences. 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. Dealing remains an option when the visible layout offers no useful improvement.
Look one move ahead
Keep these details in mind. 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. No simple rule can guarantee success on every randomly shuffled deal.
Compare a different line
Compare what each alternative reveals instead of repeating the same sequence without a new idea. Undo restores the previous card state, including flips and collected runs. Replay is useful when you want to revisit the opening arrangement of the same deal. The timer does not move backward when you undo.
Make the final decision
The suggested move may be useful for investigation without leading to a win. Hints search legal moves in the visible position. Repeatedly using Hint cycles through the available suggestions for the current position. A hint does not reveal the stock or hidden tableau cards.
Practice with purpose
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. One suit is useful for practicing rank order and the controls. Two suits introduces the difference between a descending build and a movable same-suit group.
