Scrabble Blank Tiles Strategy: How to Use Them Right

The smart way to use a Scrabble blank tile is to hold it for a bingo whenever you reasonably can, because a bingo earns a 50-point bonus and the blank makes bingos far more likely. A blank tile is the wild card of Scrabble: it scores 0 points but can stand in for any letter you choose. That combination of zero cost and total flexibility makes it the most powerful tile in the bag, and how you use it often decides the game (NASPA; Collins). Here's how to get the most out of both blanks.

What is a blank tile in Scrabble?

A blank tile is a wild tile that takes the place of any single letter. According to Wikipedia's Scrabble letter distributions, a standard English set has 2 blank tiles among its 100 tiles, and both score 0 points. The original 1938 set actually had 98 lettered tiles and was later augmented with the two blanks, which tells you they were added as a deliberate flexibility valve.

There's one rule that shapes all blank strategy. When you play a blank, you declare which letter it represents, and per the official Scrabble rules, it stays that letter for the rest of the game. You can't change it later or pick it back up. So the decision of what a blank becomes, and when to spend it, is permanent. That's why it deserves real thought rather than a reflex play.

How much is a blank tile really worth?

On the scoresheet, nothing. In practice, a lot. Scrabble expert and programmer John O'Laughlin, quoted by Stefan Fatsis in Slate, estimates the blank is worth about 25 points over an average replacement tile. Fatsis, who wrote the book "Word Freak," relays O'Laughlin's nickname for it: "the Barry Bonds of the Scrabble set." That 25-point figure is a measure of value over replacement, meaning how many extra points the blank contributes compared to a random tile.

Think about what that means. The Q and the Z are worth 10 face points each, the most of any letter, yet experts rank the 0-point blank above both. The value isn't in the tile's score. It's in what the blank lets you do: complete words you couldn't otherwise spell, and reach the seven-tile bonus far more often.

Why should you save blanks for bingos?

A bingo, also called a bonus, is when you use all seven of your tiles in a single turn. According to Wikipedia's article on the Scrabble bingo, this earns a 50-point bonus applied on top of the word's normal score. That bonus is the single biggest swing available in a normal turn, and the blank is the tile most likely to unlock it.

Here's why. A bingo needs a specific seven-letter combination. Most racks are one awkward letter short of a playable seven. A blank erases that problem, because it can become whatever letter your rack is missing. The word ends up scoring the blank as 0, but you still collect the full 50-point bonus. In Wikipedia's own example, the bingo MUZJIKS placed with the Z on a double-letter square totals 128 points including the bonus. Swap a real letter for a blank there and you'd still bank the 50.

When should you hold a blank tile?

Hold the blank when you're close to a bingo and the game is young enough to wait. If your rack already has five or six workable letters plus the blank, you're often just a draw or two away from a 50-point turn. Spending the blank on a 12-point play in that spot throws away most of its value.

Good reasons to hold:

• You have a bingo-friendly rack of common letters like E, A, S, T, R, N, or I alongside the blank. Those letters are called bingo-prone for a reason.
• It's early or mid-game, so there's time for the bingo to come together.
• The best play available right now is small, say under 20 points, and doesn't use the blank well.

Patience with a blank pays off more than patience with almost any other tile, because the upside you're waiting for is so large. A held blank is a 50-point turn waiting to happen.

When should you play a blank instead?

Holding isn't always right. Sometimes the correct move is to spend the blank now, and reading that moment is what separates strong players from stubborn ones.

Play the blank when:

• A big play is available now. If the blank completes a high-scoring word, especially across a triple word square, take the guaranteed points rather than gambling on a bingo that may not form.
• A bingo looks unlikely soon. If your other tiles are clunky and no seven-letter word is in reach, the blank's bingo potential is theoretical. Cash it in.
• It's the endgame. Unplayed tiles are subtracted from your score when the game ends, so a blank stuck on your rack at the finish is pure waste. Late in the game, get it on the board.

Which blank tile mistakes cost the most?

The most expensive mistake is spending a blank on a small, ordinary play out of impatience. If you use a blank to score 14 points early when a bit of patience would have delivered a 60-point bingo, you've effectively thrown away that 25-point-plus of equity. It won't show on the scoresheet, but it shows in the final margin.

The opposite mistake is hoarding. Holding a blank so long that you never find the perfect bingo, then getting stuck with it at the end, wastes it just as badly. Blanks reward good timing, not blind patience. And a small habit worth building: when you do play a blank, try to assign it a letter that leaves an S or a common vowel live on the board for your next turn, so the tile keeps working for you even after it's down.

What do players ask about blank tiles?

How many blank tiles are in Scrabble?

A standard English Scrabble set has 2 blank tiles out of 100 total tiles, according to Wikipedia's Scrabble letter distributions. Both blanks score 0 points and can stand in for any letter, which makes them the two most flexible tiles in the entire bag.

How much is a blank tile worth in strategy terms?

Zero at face value, but Scrabble expert John O'Laughlin, quoted by Stefan Fatsis in Slate, estimates the blank is worth about 25 points over an average replacement tile. That makes it the single most valuable tile in the game, because it turns hard-to-play racks into seven-tile bingos.

When should you hold a blank tile?

Hold a blank when you are one or two tiles away from a bingo, which earns a 50-point bonus. Because the blank makes bingos far more likely, the standard expert advice is to save it for a bingo or a very high-scoring play rather than spend it on an ordinary word.

When should you play a blank instead of holding it?

Play it when a bingo is unlikely soon, when a high-value play is available now, or late in the game when unplayed tiles count against you. In the endgame especially, a stranded blank is wasted potential, so cash it in for the best play you can find.

Can a blank tile be any letter?

Yes. A blank substitutes for any letter you choose, but once you place it on the board it stays that letter for the rest of the game, per the official Scrabble rules. You declare what it represents when you play it, and it cannot be changed or picked back up.
