Build one three-card hand
What the checker looks for
The checker first rejects a repeated physical card. It then checks matching ranks, consecutive ranks and whether all suits match. Both A-2-3 and A-K-Q are recognised; K-A-2 is not a run in this teaching model.
| Category | Recognised pattern |
|---|---|
| Trail | Three equal ranks |
| Pure sequence | Three consecutive ranks, one suit |
| Sequence | Three consecutive ranks, mixed suits |
| Colour | One suit without a sequence |
| Pair | Two equal ranks |
| High card | None of those patterns |
Changing a selection clears the prior explanation so that it is not mistaken for the result of the current hand.
Use recognition as one step in learning
This identifies one hand under the stated traditional model. It does not compare two complete hands, rank ace conventions, apply wild-card modes, inspect an Android app or predict a future deal. The tool uses no random cards or game connection.
For comparison, use the hand-order guide and the explicit ace rules. Your selections stay in the current page and are not stored or sent.
