Using Wildcards in Scrabble Solvers
Blank tiles are the most powerful pieces in Scrabble â and the most computationally interesting for word solvers. Worth zero points individually, they unlock words that would otherwise be impossible from your rack. Understanding how to use wildcards effectively in solvers transforms them from a simple search tool into a strategic weapon for vocabulary exploration and game preparation.

How Wildcard Notation Works
Every Scrabble word finder needs a way to distinguish between regular tiles and blanks in your input. The standard convention across most tools uses specific characters as placeholders.
? Question Mark
The most common wildcard symbol. ScrabbleWordsFinder.com and most major solvers use ? to represent one blank tile. Type ATRE? to search with 4 letters plus one blank.
* Asterisk (less common)
Some older tools use * for blanks. Occasionally * means "any number of letters" (pattern matching) rather than "one blank tile" â check the tool's documentation.
đĄ Input Examples
Rack: S, T, A, R, E + 1 blank â type STARE? â finds words like MASTER, STREAM, RECAST. Rack: I, N, G + 2 blanks â type ING?? â finds DOING, BRING, SWING, THING, and hundreds more.
The 26Ã Branching Problem
When a solver encounters a ? in your input, it doesn't just check one path through the dictionary tree â it checks all 26. This is because the blank could represent any letter from A to Z, and the solver must explore every possibility to find all valid words.
7 tiles
No blanks: ~5,040 paths
6 + 1?
One blank: ~130K paths
5 + 2?
Two blanks: ~3.4M paths
<100ms
Still fast (pruning)
Despite this exponential growth in search space, modern solvers handle it efficiently through tree pruning. If the dictionary has no words starting with "QX", the solver abandons that branch immediately â even if the blank makes Q and X both available. This aggressive pruning keeps response times under 100ms on ScrabbleWordsFinder.com, even with two blanks.
đ§Š How the Solver Processes a Blank
Parse input: Identify which characters are regular tiles and which are wildcards (?).
Expand blanks: At each tree node where a blank is used, branch into all 26 child nodes that exist in the dictionary trie.
Track assignment: Record which letter the blank represents in each found word (needed for scoring).
Score correctly: Assign 0 points to the blank's position, regardless of which high-value letter it represents.
Scoring Differences with Blanks
The critical rule: blank tiles always score zero. This has significant implications for how solvers rank results and how you should evaluate the words they find.
â QUIZ with real Q, U, I, Z
Score: Q(10) + U(1) + I(1) + Z(10) = 22 points. Full tile values apply when all letters come from actual tiles on your rack.
⥠QUIZ with blank as Z
Score: Q(10) + U(1) + I(1) + blank(0) = 12 points. The blank acting as Z contributes nothing â a 10-point loss compared to the real Z.
đ§ Solver Score Display
Good solvers (like ScrabbleWordsFinder.com) show scores adjusted for blank usage. When a blank is used, the displayed score reflects 0 for that position. Some tools highlight which letter is the blank so you can see the scoring impact at a glance.
Strategic Tips for Wildcard Searches
Knowing how to use wildcards in a solver is one thing. Using them strategically to improve your game is another. Here's how experienced players leverage blank tile searches during study sessions.
Save blanks for bingos: The consensus among strong players is that blanks should be saved for 7-letter words (50-point bonus). Search your rack + ? to see if a bingo is available before using the blank on a shorter word.
Don't waste blanks on common letters: Using a blank as E or S is usually inefficient â you'll likely draw those naturally. Reserve blanks for letters that complete rare combinations or enable premium square access.
Practice "blank as X" drills: Enter your strongest racks + ? into the solver and study which letter assignments yield the highest scores. Over time you'll recognize the patterns without needing the tool.
Check both options: If you have two blanks, search with both (RACK??) but also try RACK? with just one â sometimes playing one blank now and saving the other yields better long-term value.
The real power of wildcard searches in tools like ScrabbleWordsFinder.com is revealing possibilities you'd never spot at the board. A rack of AEIRST? might look average â until the solver shows you that the blank as N gives NASTIER, RETINAS, RETAINS, and STAINER. That's knowledge you carry into your next game.
