Write the rule card first
| Question | What must be settled |
|---|---|
| Target | Is the target exactly 999 or closest to it? |
| Card values | How are tens, faces and aces converted? |
| Order | May the three digits be rearranged? |
| Distance | What happens above the target or on equal distance? |
An original worked exercise
For an original teaching model only, let faces count as zero, aces as one and other ranks use their printed digit. Allow descending rearrangement and compare the resulting number. The cards 9♠ 8♥ K♦ form 980; 9♣ 7♦ 6♠ form 976. The first is nearer to 999. This arithmetic illustrates the need for a rule and is not asserted to match any current app.
Test an edge case before starting
Pick a second example that stresses the rule: an ace, a wild card, equivalent final hands or an extra-card choice. Ask every learner to explain the result. A disagreement is useful evidence that the written rule needs more detail. Resolve it before dealing more examples.
Classic tools have a boundary
The browser hand comparator supports three-card classic no-joker hands only. It must not be used as a decision engine for this variant unless the exercise reduces to a supported classic hand after an explicitly defined selection.
