A guide to your next move.
Look under the visible cards
Keep these details in mind. A longer visible run is not automatically better than a move that opens the tableau. You cannot know the identity of a hidden card before it is exposed. A move that reveals a hidden card gives you another fact to work with. Compare possible moves by what they uncover as well as by the length of the sequence they create.
Value an empty column
Here is what to know. A whole-column move into another empty column does not reveal anything new on its own. 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.
Favor matching suits
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. Same-suit descending cards remain movable as a group. Look for ways to join matching segments without burying a card you need elsewhere.
Plan how to separate suits
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. Only the same-suit descending segment at the bottom moves together.
Plan around Kings
On this website, the following points apply. A group beginning with a King has the same limitation. Placing a King in your last empty column may reduce your immediate rearrangement options. A King requires an empty column because there is no higher rank. Moving a King can still be useful when it uncovers an important hidden card.
Pause before dealing
On this website, the following points apply. Dealing remains an option when the visible layout offers no useful improvement. Keeping all columns occupied is a requirement for using the stock. A stock deal adds one card to every column and may disrupt useful sequences. Check whether a visible move can expose a card or join matching suits before you deal.
Compare follow-up choices
Ask what a move will let you do next rather than considering only the first destination. No simple rule can guarantee success on every randomly shuffled deal. Moving a small segment may release a second move that was previously blocked. Try to leave more than one useful destination when the layout allows it.
Use undo as a lesson
The timer does not move backward when you undo. 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. Compare what each alternative reveals instead of repeating the same sequence without a new idea.
Treat hints as options
On this website, the following points apply. A hint does not reveal the stock or hidden tableau cards. Hints search legal moves in the visible position. Repeatedly using Hint cycles through the available suggestions for the current position. The suggested move may be useful for investigation without leading to a win.
Practice with purpose
On this website, the following points apply. 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. Four suits gives you more suit conflicts to resolve using the same rules.
