Declaration Practice: a guide for your next round
Begin with the objective. Check whether a complete 13-card hand can satisfy every declaration requirement. Check the relevant controls before continuing. Take a moment to read the table. 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.

An example to follow
Example hand: 3♥ 4♥ Joker 5♥ 4♣ 5♦ 9♥ 5♥ 9♠ 5♣ 9♣ 5♣ 5♠. Wild rank 4. All thirteen cards can be split into legal non-overlapping melds, including two sequences and a pure sequence. Take the next action only when the current step is clear.
