Fill-Ins · Word Fit Puzzles

Review by eFreeware

Fill-Ins is a word puzzle game from Razzle Puzzles, published on Google Play under the Word category. It takes the crossword grid you already know and removes the clues, leaving you with a list of words to fit into the diagram. The main reason to consider it is volume: the developer describes thousands of puzzles, and the app has been installed more than a million times with a 4.7 average from over 16,000 ratings.

It is free to install and supported by ads. There are no in-app purchases, so nothing inside the game asks you to spend. For anyone who treats puzzle solving as a daily habit rather than a one-off download, that combination is the pitch: a large catalog, a small learning curve and no paywall between you and the next grid.

A crossword grid with the clues taken away

The premise is simple enough to explain in a sentence. Each puzzle gives you a set of words and an empty grid, and your job is to arrange every one of those words so the whole diagram fits together. The words interlock the way crossword answers do, but nothing tells you where any particular word belongs. The only information you have is the list itself, plus the shape of the grid.

That change alters how the puzzle feels. In a standard crossword, a clue points you toward an answer and the grid confirms it. Here, the words are all known from the start; the work is spatial. You are looking for the one arrangement where lengths, crossings and available space all agree. The developer compares it to a crossword but with words in place of clues, and that is a fair way to think about it.

Difficulty is handled through word length rather than obscure vocabulary. Easier grids mix longer and shorter entries, which gives you more places to start. The hardest ones, according to the developer, contain only three- and four-letter words. That sounds gentler than it is: when every entry is the same rough size, the grid offers far fewer footholds and the arrangement becomes the entire challenge.

How a grid comes together

A puzzle begins with a small piece of help already in place. The developer places the initial letter of every word somewhere on the grid before you start. Those letters are anchors: they tell you where a word begins, even though they do not tell you which direction it runs or which word it belongs to. From there you work by elimination, testing a word against the space and the letters it would have to cross.

The rhythm of a solve tends to run in phases. Early on, the longer words are easiest to place because they have fewer viable positions. The middle is the slow part, where several candidates fit the same slot and you have to commit to one and see whether the rest of the grid still closes. The end is usually quick, because by then most of the letters are fixed and the remaining words have only one place to go.

Because the starting letters are given, a stuck grid is rarely a dead end. It is more often a case of having placed one word incorrectly several steps back. That is the appeal for solvers who like logic puzzles as much as word puzzles: the vocabulary load is light, and the satisfaction comes from the moment the arrangement locks into place.

Hints, solve times and a long-running catalog

When a grid refuses to resolve, the game offers hints. The developer describes the supply as unlimited, which matters more than it might sound: a hint system that runs out turns a difficult puzzle into a wall. With no cap, you can take as much or as little help as you want on any given grid, and the choice stays yours rather than the game's.

The app also tracks your solving history. Best and average times are recorded, so you can see whether a particular difficulty level is getting easier for you over weeks and months. It is a modest feature, but it gives the catalog a sense of progression that a plain list of puzzles would not have. Solvers who enjoy measuring themselves against their own past results will get more out of it than those who just want to clear grids.

The catalog itself is the long-term draw. Thousands of puzzles, spread across a range of difficulties, means the app is not something you exhaust in a weekend. Fill-Ins was first released in September 2016 and the developer issued an update in February 2026, so the game has been kept current over a long stretch rather than left as a snapshot.

Free, ad-supported, nothing to buy

Fill-Ins costs nothing to download and displays ads. There are no in-app purchases, which keeps the experience straightforward: you will not be offered hint packs, puzzle bundles or a subscription while you are midway through a grid. The trade is that advertising is part of the package.

For a free puzzle game with a catalog this size, that arrangement is easy to understand. You are paying with attention rather than money. Whether that suits you depends on how much you mind interruptions during a solve, and that is a personal threshold rather than something the app can settle for you.

One practical point worth noting: the game can be played online or offline. That makes it usable in places where a connection is unreliable, and it means a puzzle you have started does not depend on a signal to continue. The developer also supports both phones and tablets, and the content rating is Everyone.

A steady fit for clue-free solvers

Fill-Ins is a good match for people who enjoy crosswords but find the trivia side of them tiring. There are no clues to decode here, no obscure names to recall and no penalty for not knowing a particular fact. Everything you need is on the screen, and the puzzle is solved by arrangement rather than recall. If you like the shape of a crossword grid but want the vocabulary pressure turned down, this is built for that.

It also suits solvers who want a long runway. Thousands of puzzles at multiple difficulty levels, an unlimited hint supply and a stats tracker add up to something you can return to regularly without running dry. The absence of in-app purchases keeps the relationship simple, and offline play means it works wherever you happen to be.

The caveats are honest ones. Ads are present. The hardest puzzles lean on short words rather than long ones, which changes the challenge in a way some solvers will find less satisfying than a traditional crossword. And the game is a single, focused activity: it does one thing, and it does that thing across a very large set of grids.

On balance, this is an easy recommendation for anyone who wants a free, generous supply of word fit puzzles with help available when needed. It is not trying to be more than it is, and for a puzzle game that is usually the right call.
