Distribution Puzzles

At a glance 10 rules

1. 1Grid, then direct cluesOne row per person, one column per attribute. Enter each direct 'X has Y' clue, then cross Y off for everyone else and X's other options.
2. 2Last option standingNegative clues only cross out. When a person has one value left, or a value has one person left, it is theirs: three crosses in a row of four fill the fourth.
3. 3Link attributes firstA clue like 'the Kochi student learns Japanese' joins two attributes, not a name: pair the attributes up first and put a person on the pair later.
4. 4Numbers as values'A paid ₹10 more than B' or 'A and B together paid ₹70' allows only a few pairs: list them, and keep the pair that fits every other clue.
5. 5Either/or and 'could be'Run both cases of an either/or clue side by side and drop the one that breaks a clue. 'Could be true' needs one valid case; 'must be true' needs all of them.
6. 6Two items eachWhen each person takes two items, count free slots: a pair that must stay together (laundry with ironing) can only go to someone with two slots open.
7. 7Teams and groupsSame-team clues glue people into blocks and different-team clues split them. Place the biggest block first and let the team sizes fill the rest.
8. 8Selection rules'If P is in, Q is in' also means 'Q out, so P out', never 'Q in, so P in'. To test whether someone must be in, try to build a valid group without them.
9. 9Shares with a totalWith a fixed total and order clues (A more than B, B more than C), list every split that fits; a share that is the same in all of them is fixed.
10. 10Biggest and smallest shareDifferent whole numbers, fixed total: to push one share up, give every other share the least it can take, even those above it. To keep the top share small, keep all of them close.
