Rebus Squares Are Back and Solvers Have Opinions

There is a moment in a rebus puzzle when the grid stops making sense. You have four crossings you are certain of, and they demand that one square hold the letters H, E, A and R all at once. Either you have made a mistake, or the puzzle has broken a rule you thought was inviolable.

It has not, of course. It has just told you what kind of puzzle it is, roughly two thirds of the way through, and everything you had written up to that point needs revisiting. Solvers either love this or find it insufferable, and there is very little middle ground.

What a rebus actually is

A rebus square is a single cell that contains more than one letter, or occasionally a symbol standing in for a word. The convention appears in daily American crosswords most often on a Thursday, which is why Thursday has a reputation for trickery out of proportion to its difficulty rating.

The trick is only interesting when the multi-letter squares form a pattern. A puzzle where seven random cells hold two letters each is not a rebus theme, it is a mess. A puzzle where every rebus square holds the name of a planet, and the squares sit in orbit around a central entry, is a theme. The difference is whether the solver, having found the first one, gains any purchase on the rest.

A rebus is a rule change announced in the middle of the game. The only defence is to make the new rule findable.

Why solvers argue about it

Two complaints come up repeatedly, and both are fair.

The first is technological. On paper you can write four small letters in a box; in an app you often cannot, or you can but the interface fights you. A trick that works beautifully in print becomes an argument with a text field on a phone. Constructors do not control the app, but they should know that a rebus costs digital solvers more than it costs paper solvers.

The second is about fairness. A rebus square is only fair if both of its crossings are solid. If the Across entry needs the rebus and the Down entry is an obscure proper noun, the solver has no way to confirm the discovery, and the puzzle has moved from clever to arbitrary. This is the failure mode that generates most of the complaints.

Four rules for cluing a rebus

• Both crossings must be gettable. Every rebus square sits at the intersection of two entries, and at least one of them should be solvable cold.
• Signal the change somewhere. A revealer entry, a title, or a clue that reads oddly on purpose. Not a note in the byline that half the solvers will never see.
• Keep the pattern consistent. If the first rebus holds a three-letter word, the rest should too. Mixed-length rebus squares in one grid feel like a bug.
• Put one where it will be found early. If all your rebus squares are in the bottom-right, the solver spends thirty minutes convinced they have made an error.

The case for the trick

For all that, the rebus is one of the few devices that lets a 15x15 grid contain more than 225 letters, and it is the closest an American-style crossword gets to the misdirection that British cryptics take for granted. The best rebus puzzles produce a specific and rare feeling: not the satisfaction of knowing an answer, but the satisfaction of realising what sort of thing you are looking at.

That feeling is why the device keeps coming back despite the complaints. It is also why it should be rationed. A constructor who uses a rebus twice a year will be remembered for both. One who uses it monthly is just making the grid harder.

Where to see them

The general history of the crossword records the rebus as a mid-century innovation that never quite settled into routine, and the searchable grid database at XWord Info lets you filter published puzzles by whether they used one. If you want a worked example without spoiling a puzzle you have not solved, the daily answer write-ups at this NYT answers archive usually explain how a rebus resolved, and the Wall Street Journal puzzle archive is a good second source since the WSJ uses the device on a different schedule.

Solve a few. Then decide which camp you are in, because everyone eventually picks one.
