Clarifying the way this game works
What is the aim?
Recognise valid three-card or four-card sets using different natural suits. Take a moment to read the table. Use another round to revisit a decision.
How do I use the controls?
Tap the answer buttons or selected card; the deadwood exercise uses a numeric input. Next question appears after an answer. Keep the active rule in mind. The same rule applies on a phone and on a computer.
Which format is available?
500 stored and rule-checked questions; ten questions per session. Questions can repeat across sessions. Practice is solo, with no rating, cash reward or account. For a calm first round, focus on one decision. The same rule applies on a phone and on a computer.
What should I check before a move?
Multiple decks do not make duplicate natural suits valid within one set. A clear plan starts with the current position. Use another round to revisit a decision.
Can you give an example?
Q♠ Q♥ Q♦ is a set. Two natural Q♠ cards and Q♥ are not a valid set. Look at the complete hand before deciding. The same rule applies on a phone and on a computer.
How many questions are available?
This exercise contains 500 stored questions. A session selects ten without repeating within that session. Treat this as a chance to practise one rule. Check the relevant controls before continuing.
Can I change a submitted answer?
No. Read the explanation, then continue. Start another session to practise again. Work at your own pace. The same rule applies on a phone and on a computer.
Are the answers checked against the rules?
Natural cards in a set have one rank and different suits; wild cards fill missing positions. Before making a move, check the cards in view. Return to the explanation when a decision is unclear.
Will I always see new cards?
No. The bank is finite, so another session may include a previously played question. Treat this as a chance to practise one rule. Take the next action only when the current step is clear.
What does the score measure?
The score is the number of correct answers in this ten-question session. It is not a skill certificate or a prediction of match results. Work at your own pace. Check the relevant controls before continuing.
