A guide to your next move.
Look under the visible cards
The key details are straightforward. 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. 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.
Value an empty column
Here is what to know. Consider the next destination before filling your only 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. A whole-column move into another empty column does not reveal anything new on its own.
Make groups that can move
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. A shorter matching group can be easier to reuse than a longer mixed-suit build.
Use mixed builds deliberately
Keep these details in mind. 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. 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.
Know the limited destination
On this website, the following points apply. A group beginning with a King has the same limitation. 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. Placing a King in your last empty column may reduce your immediate rearrangement options.
Pause before dealing
On this website, the following points apply. 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. Dealing remains an option when the visible layout offers no useful improvement. Keeping all columns occupied is a requirement for using the stock.
Look one move ahead
Here is what to know. 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. Ask what a move will let you do next rather than considering only the first destination.
Use undo as a lesson
Here is what to know. 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. The timer does not move backward when you undo. Compare what each alternative reveals instead of repeating the same sequence without a new idea.
Make the final decision
Keep these details in mind. 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.
Choose a comfortable challenge
On this website, the following points apply. Four suits gives you more suit conflicts to resolve using the same rules. Two suits introduces the difference between a descending build and a movable same-suit group. 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.
