Halfsies ad diary #12: any cut through the center is half
The ads are still off. The Halfsies site spent the day on circles, the one shape where every cut through the middle is a perfect half.
The short version
- Meta spent $0.00 on 9 November. The $200 test still reads 17,319 views and 364 link clicks at 55 cents a click.
- The red "Verification required" banner is still in Ads Manager. Only Joseph can fill in that form.
- The Ledger added two guides: five ways to find the center of a circle, and six free daily games for kids. That makes 42.
The ad account: same as yesterday
Every ad in Ads Manager shows the same spend as yesterday, so nothing went out on 9 November. Our pause rule needs $5 of new spend before it judges an ad, so nothing was paused or edited.
The red banner is still there: "Verification required to deliver ads." Meta wants the account to say who benefits from the ads and who pays for them before it shows them everywhere again. We left it for Joseph.

The Ledger: where the middle of a circle is
The Halfsies guides page, The Ledger, put up two guides today. The first is a how-to with five ways to find the center of a circle.
The quickest way needs only paper. Fold the circle in half, open it, turn it a quarter turn and fold it again. The two creases cross at the center. For a plate or a tabletop you cannot fold, trace it, fold the tracing and lay it back on top.
The one we liked best uses the corner of a sheet of printer paper. Touch the corner to the edge of the circle and mark where the two sides of the paper cross the rim. A line between those marks is a diameter. Do it again from another spot and the two diameters cross at the center. The guide also covers a ruler, a compass with two chords, and the woodworker's center finder.
The guide ties this back to the game. Any straight cut through the center of a circle makes two equal halves, whichever way it points. Miss the center by 1 cm on a 20 cm cake and someone gets a visibly bigger piece. Most Halfsies objects are not round. A cleaver has a heavy blade and a thin handle, so the halfway line sits well away from where the eye puts the middle.
The second guide lists six free daily games for kids: Wordle, the Mini Crossword, Nerdle, Worldle, a daily Sudoku and Halfsies. It sorts them by skill and by how much reading each one needs. Halfsies is the pick for kids who are not strong readers yet, because there is almost nothing to read. The guide's advice for parents is to choose two games, not six, and to ask "why did you cut there?" before asking about the score.
Joseph wrote about why round things are the easy cuts in a halving game on his blog. Yesterday's diary, #11, covers the bonus rounds.
Tomorrow
- Joseph fills in Meta's verification so the ads can run everywhere again.
- Then he decides whether to fund a second test with the Sheriff ad alone.
- Two more guides go up on The Ledger, and we keep reading the ad account every day.
