IX7: Five Correct Examples Still Leave Room for One Wrong Rule

Test a tempting rummy rule against a counterexample. Ask Saraswati Maa for the patience to check what the examples prove, rather than stop at a familiar pattern.

“Three cards of the same suit make a sequence.”

It sounds convincing after several examples work. For IX7 readers, the difficulty is not remembering the examples; it is noticing the extra condition they all happened to satisfy.

Try this short rummy learning exercise before reading the answer.

2♠ 3♠ 4♠
4♥ 5♥ 6♥
7♦ 8♦ 9♦
9♣ 10♣ J♣
J♠ Q♠ K♠

All five groups are natural sequences. They have one suit within each group, but they also have consecutive ranks. A23's explanation of sequences includes both conditions.

If you notice only the shared suit, your proposed rule leaves out something present in every successful example.

Give the proposed rule a difficult example

4♠ 6♠ 9♠

These are three spades. They satisfy the proposed wording, yet their ranks are not consecutive. As the three natural cards shown, they do not make a sequence.

This single group is enough to disprove “same suit is sufficient”. You do not need six failed examples to outweigh the five successful ones, because the claim said that the condition always suffices.

A prayer for the patience to test

Saraswati Maa is approached for knowledge and discernment. Here the wish is to remain willing to examine a comfortable conclusion, especially when your first few examples seemed to confirm it.

At her offering area on Ishta Mel, offer white flowers, books, fruits, kheer and deepak together.

ॐ ऐं सरस्वत्यै नमः

Maa, accept my offering. Give me patience to examine the rule I am about to repeat. Let me welcome the example that reveals what I missed, and grant me understanding to correct my words.

Now write the corrected statement: a natural sequence contains three or more consecutive cards of one suit, with no joker replacing a missing card.

Return to all six groups. The corrected conditions explain why the first five work and why the last does not. That is stronger than merely remembering which pictures received a tick.

For an IX7 reader, the useful habit is to ask, “What would expose a missing condition?” Sometimes the example that does not work teaches more than another example that does.
