How to Solve it
A step-by-step walkthrough of this puzzle
- 1
Plus-Minus Grades 📋
A+, B-, and AB+ look like letter grades, with plus and minus signs marking stronger or weaker results. That is a reasonable first read because all three fit the familiar grading format.
- 2
O+ Changes Course 🔄
O+ is described as the most common, which does not fit a grading scale. The letters and signs instead identify blood groups and Rh status.
- 3
The Donor Clue 🚑
O- is called the universal red cell donor, confirming the blood-group pattern. Each clue names a type based on its ABO group and positive or negative Rh status.
Blood types labeled by ABO group and Rh status.

What connects A+, B-, AB+, O+ (the most common) and O- (universal red cell donor)? That's Pinpoint #890, the LinkedIn puzzle from Wednesday, October 7th, 2026.

What connects A+, B-, AB+, O+ (the most common) and O- (universal red cell donor)?
The answer to Pinpoint #890 is Blood types. Every clue in the set — A+, B-, AB+, O+ (the most common) and O- (universal red cell donor) — belongs to “Blood types”, which is the thread you're looking for.
If you got there in one or two clues, the giveaway was almost certainly A+ paired with B- — that combination rules out most of the categories a single word could belong to. The clue-by-clue breakdown above the fold shows exactly where each word lands.
How Pinpoint works
| Rule | Detail |
|---|---|
| Goal | Guess the category that connects all five clue words (for example, “Apple, Dell, Acer, HP” → computer brands). |
| Clues reveal one at a time | You start with one word and get another after each wrong guess, up to five — the fewer you need, the better your score. |
| Guesses | Type the category; the game tells you if you're right. You have a limited number of tries. |
| Reset | A new Pinpoint puzzle drops every day at midnight Pacific Time (3:00 a.m. Eastern). |
Solving a clue set like this one
- Put the first two clues side by side before guessing anything. A+ on its own fits a dozen categories; A+ plus B- usually fits one or two.
- If your first theory dies on clue three, don't patch it — throw it out. A theory that needs an exception for one clue is the wrong theory.
- Check for a shared word before you check for a shared topic. Pinpoint loves sets where every clue sits in front of (or behind) the same hidden word.
- Say each clue out loud. Homophones and phrases hide in plain sight when you only read them.
How Pinpoint scoring works
You see one clue to start and earn another after every wrong guess, up to five. Solving on clue one is the best possible result and solving on clue five still counts as a win, so there's no reason to rush a guess you're not confident in — a wrong answer costs you a clue you can't get back.
