Learn your way around Joker Sequence Practice
A clear plan starts with the current position. Decide whether natural cards and available jokers can complete one same-suit sequence. Use another round to revisit a decision. Keep the active rule in mind. Start a 10-question session. Read the visible rule label and wild rank, if shown. Check the relevant controls before continuing.
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.
A focus for your next round
Treat this as a chance to practise one rule. A joker can fill a missing rank, but fixed natural cards must fit one suit and a consecutive interval. Return to the explanation when a decision is unclear.
Aim for this result

Your inputs
Tap the answer buttons or selected card; the deadwood exercise uses a numeric input. Next question appears after an answer. Use another round to revisit a decision. Keep the active rule in mind.
A useful example
Example hand: A♠ 6♠ Joker. Wild rank 1. These cards fit consecutive positions in one suit; a joker can fill a missing position. Take the next action only when the current step is clear.
Avoid this misunderstanding
Before making a move, check the cards in view. A wild substitute cannot erase a conflicting fixed suit or duplicate fixed rank. The same rule applies on a phone and on a computer.
