Crossmath® - Math Puzzle Games

Review by eFreeware

Crossmath is a puzzle game from Guru Puzzle Game in which arithmetic meets the crossword grid. Instead of fitting words into intersecting rows and columns, you fit numbers so that every equation reads correctly, using addition, subtraction, multiplication and division. It is free to install, it carries ads, and it offers in-app purchases.

The main reason to consider it is the sheer volume of structured practice it puts behind a simple idea. There are four difficulty tiers, a daily puzzle, an Endless Mode with a global leaderboard, and a set of optional aids, all wrapped around a loop that takes a minute or two per board. With more than 50 million installs and a 4.8 average across roughly 885,000 ratings, it has clearly found a large audience among people who like their puzzles numerical rather than verbal.

I would describe it as a game for players who enjoy sudoku-style logic but want something more arithmetic. The developer pitches it as a way to train your brain and relax at the same time, and that combination of light pressure and short sessions is exactly what the structure supports.

How the number grids actually work

Each level presents a grid of intersecting equations. Some cells are filled in for you; the rest you complete by choosing numbers that satisfy every row and column at once. Because the equations cross, a value you place for one clue constrains the others, which is what turns a plain arithmetic exercise into a logic problem. You are not just calculating, you are narrowing down possibilities until only one arrangement works.

The four operations are all in play, so the difficulty comes from two directions at once: the size of the numbers and the mix of operators. A grid built mostly on addition and subtraction stays gentle, while one that leans on multiplication and division forces you to think about factors and multiples before you commit to a digit. That is a meaningful step up from the kind of number puzzle where each clue stands alone.

Mistakes are part of the process, and the developer handles them generously. Undo is unlimited, so a wrong entry costs you a tap rather than a restart. That single design decision changes the feel of the game considerably: you can experiment, follow a hunch and back out of it without penalty, which suits players who like to reason their way forward rather than plan every move in advance.

Difficulty tiers, daily puzzles and Endless Mode

The progression is built around four difficulty settings: Easy, Medium, Hard and Expert. That gives you a straightforward way to match the game to your mood or your ability on a given day, and it means the same core mechanic can serve a casual solver and someone who wants a genuine workout. Alongside that sits a daily challenge, one puzzle per day, which is the sort of feature that turns a puzzle game into a small routine rather than a binge.

Endless Mode is the most interesting variation. In this mode, the game does not check your errors as you go; you submit your answers at the end and find out how you did. That removes the running feedback that normally tells you when something is wrong, so you have to hold the whole grid in your head and be confident in your reasoning. The developer ties it to scoring, with a higher score for completing more levels without mistakes, and it feeds the global leaderboard where you can see how you compare with other players.

There are also time-limited themed events and a Star Race in which you compete against other players for rewards. The events come with badges to collect, which gives the game a collectible layer on top of the puzzle solving. A recent update added a Brains rank to the leaderboard, so there is now a named standing to chase rather than just a position number. None of this changes how the puzzles work, but it does give regular players something to aim at beyond finishing the next board.

Aids, settings and how the game tracks you

Power-ups are available to help you move faster, and the developer lists hints and advanced notes among them. Read that as a way to get unstuck when a grid resists you, rather than as a shortcut through the game. Since the game offers in-app purchases, some of these aids may be the kind of thing tied to spending.

The presentation options are unusually considerate for a puzzle game. Large fonts are there for anyone who finds small digits hard to read, and dark mode makes the grid comfortable to look at in low light, which matters if you like to play before sleep. These are small settings, but on a game you might open every day they are the difference between comfortable and irritating.

Statistics round out the package. The game keeps a record of your play so you can watch your accuracy and scores develop over time. For a game built on arithmetic, that record is more useful than a simple high score: it shows whether the harder tiers are actually getting easier for you. The developer frames the whole thing as a way to improve math skills, and a progress log is the part of the design that makes that claim at least plausible rather than just promotional.

Ads, purchases and what they mean for play

Crossmath is free to download and supported by advertising, and it also offers in-app purchases. That is the full picture the developer provides. I would not read the presence of purchases as a paywall in front of the puzzles, but it does mean the experience includes commercial interruptions and optional spending.

For a game you might play in short bursts, ads are the main thing to weigh. They do not change the puzzles themselves, but they do sit between you and them, and how tolerable that is depends entirely on how often you play. If you are the sort of person who opens a puzzle game for five quiet minutes, a free game with advertising is a reasonable trade; if interruptions break your concentration, that is the cost of the free version.

The in-app purchases are the other consideration, particularly around power-ups. If hints and notes are the sort of help you lean on, you may find yourself weighing whether to pay for them. The daily puzzle and Endless Mode are described as modes rather than purchases, so the core loop stands on its own.

The player this grid is built for

The clearest fit is someone who already enjoys logic puzzles and wants arithmetic to be part of the challenge. If you like the process of elimination in a number grid and you are comfortable with multiplication and division under a little time pressure, the four difficulty tiers give you room to start gently and work upward. The daily puzzle is the strongest hook for that player: a single board, once a day, is an easy habit to keep.

Competitive players have a separate reason to stay. Endless Mode rewards clean runs, the leaderboard ranks you against everyone else, and the Star Race and themed events add periodic targets. If you are the type who checks a ranking after every session, there is enough here to keep you coming back beyond the puzzles themselves.

Players who want a calm, low-stakes diversion are also served, provided they accept the advertising. Unlimited undo means there is no punishment for guessing, large fonts and dark mode make long sessions comfortable, and the statistics give a quiet sense of progress. It is not a game that demands speed or reflexes; it asks you to think, and it lets you do so at your own pace.

Is Crossmath worth installing?

For anyone who likes number puzzles and wants a free game with real depth, Crossmath is easy to recommend. The core mechanic is well chosen, the four difficulty tiers give it range, and the daily puzzle plus Endless Mode and leaderboard give it reasons to stay installed. The developer has also kept the experience comfortable with large fonts, dark mode and a progress log, which suggests attention to how people actually play puzzle games over months rather than days.

The reservations are straightforward. It is free with ads and in-app purchases, so you are trading a small amount of interruption and optional spending for the content. The game is also narrowly focused on arithmetic grids; it does not try to be anything else, and its appeal depends on whether that specific challenge appeals to you.

If you want a puzzle game that fits into short sessions, rewards careful thinking and gives you a clear ladder of difficulty to climb, this is a strong choice. If you prefer word puzzles, or you need an entirely uninterrupted experience, the free model will be the deciding factor. For everyone in between, it is worth installing and trying the daily puzzle first.
