Why isn't 'Things that Use Electricity' the answer?
While many of the items do use electricity, not all of them *require* it. A simple coffee pour-over does not need electricity to filter coffee.

If you found yourself staring at your phone trying to crack Pinpoint #556, you're not alone! This one hinged on connecting seemingly disparate items like Vacuum cleaner and EMAIL SOFTWARE. The key was realizing that all the clues are THINGS WITH FILTERS.
Let's break down how to arrive at this surprisingly clean solution.
I'll admit, this one had me spinning for a bit.
My first thought jumped to "Things that need electricity," but that felt too broad.
Then, I briefly considered "Things found in an office," driven by the EMAIL SOFTWARE clue, but that felt like a RED HERRING.
I started listing out what each item *did*.
The Vacuum cleaner filters dirt, the Aquarium filters water, the Car engine filters air and oil...
a pattern started to emerge.
But the Drip coffee maker and email software threw me off again!
Could there be two different filter types?
Finally, the realization hit: coffee filters and spam filters!
All the items have something that actively filters something else.
That's when "Things with filters" clicked, and I felt like I'd finally vacuumed up the solution.
All five clues point to contexts where a literal or logical filter is essential.
Vacuum cleaners rely on HEPA or cyclone filters to catch fine particles so they don’t recirculate.
Aquariums need mechanical/biological filters that continuously remove debris and convert ammonia.
Car engines use multiple filters (air, cabin, oil, fuel) to protect components and keep combustion clean.
Drip coffee makers pass water through a paper or metal filter to extract flavor while holding back grounds.
Email clients run spam filters (rule‑based and ML) to block unwanted messages and surface legitimate mail.
Today’s set is a classic single‑theme group: every item depends on a filter.
Two physical systems (vacuum, engine), one water system (Aquarium), one kitchen device (coffee maker), and one software system (spam filtering) echo the same idea across domains.
The answer was Things with filters!.
Things with filters!
| Clue | Early read | Resolved read | Why it works |
|---|---|---|---|
| Vacuum cleaner | Same first broad read as the rest of the board | "Vacuum cleaner" | A vacuum cleaner uses a filter to trap dust and debris, preventing them from recirculating. |
| Aquarium | Same first broad read as the rest of the board | "Aquarium" | An aquarium filter removes waste and impurities from the water, keeping the fish healthy. |
| Car engine | Same first broad read as the rest of the board | "Car engine" | A car engine uses air, oil, and fuel filters to ensure proper combustion and prevent damage. |
| Drip coffee maker | Same first broad read as the rest of the board | "Drip coffee maker" | A drip coffee maker uses a paper or metal filter to separate the coffee grounds from the brewed coffee. |
| Email software (targeting spam) | Same first broad read as the rest of the board | "Email software (targeting spam)" | Email software uses spam filters to block unwanted messages from reaching your inbox, a digital filter! |
Don't be afraid of abstract connections
The EMAIL SOFTWARE clue highlights that the connection doesn't always have to be physical. Think conceptually! The 'filter' in this case is a digital one, blocking unwanted emails.
Break down each item individually
As I started listing out what each item *did*, as mentioned in the 'solutionEmergence' section, the pattern emerged. This is especially useful when items like DRIP COFFEE MAKER seem out of place.
Consider multiple functions
The CAR ENGINE clue could have led down a path of 'things with wheels,' but focusing on its filtering function was key. Remember that items can have multiple characteristics, but only one connects them all.
The word "targeting" can be a huge help!
The email software clue specified "targeting spam". The word "targeting" strongly suggests some form of filtering. It acts as a nudge in the right direction.
While many of the items do use electricity, not all of them *require* it. A simple coffee pour-over does not need electricity to filter coffee.
This refers to the spam filter function built into most email programs. It filters out unwanted messages based on various criteria.
A vacuum cleaner uses a filter to separate the dust and dirt it sucks up from the air, preventing those particles from being blown back into the room.
