FroGames — Moments You'll Remember
Ten digits, a grid, and sums that must add up. Sounds easy — until you realize there's only one solution.
What it's about
Fit the digits and make the sums add up
IQ Digits is the travel-friendly number puzzle from the acclaimed SmartGames IQ series. You need to place digit-shaped tiles, from 0 to 9, onto the board. The goal is to fit them all so that the sums match what the challenge requires. It's not just a fitting puzzle — it's logic, deduction, and a touch of math.
Each challenge starts with some digits already in place. You have to fit all the others onto the grid, respecting the indicated conditions: certain spaces must yield a precise sum, and often, only by deducing which pieces can form it will you find the right path. In IQ Digits, every challenge has only one solution, found at the back of the booklet.
One hundred and twenty challenges of increasing difficulty, from age 7 up to expert level. No luck, no dice: just concentration, logic, and number sense. The compact case with a transparent lid makes IQ Digits the perfect companion to tuck into your bag and pull out anywhere.
The twist is here: it's not enough to fit all the pieces. The numbers must also add up. It's a fitting puzzle and a small mathematical brain-teaser at the same time.
The secret of IQ Digits in one line
That moment when the last digit slides into place, you close the lid, and everything adds up perfectly on the first try. Ten minutes stolen on the train, complete satisfaction.
From the gaming experience
IQ Digits
On the board
What you put into play with each challenge
Digits 0–9
Colored number-shaped tiles. You fit them all onto the grid: it's the heart of the fitting puzzle.
Sums to add up
It's not enough to fill the grid: certain sums must match what the challenge asks for. This is where the math comes in.
The grid
The compact board with a transparent lid. Each challenge starts with some digits already fixed in their places.
Logic and deduction
In many challenges, you have to figure out which pieces can form a certain sum and deduce where they go. Think first, place later.
A boring wait, ten minutes, and a challenge you thought impossible ends with perfect sums. It always happens with IQ Digits.

What happens when you play
Not the rules. The experience.
Choose your next challenge
Open the booklet and choose a number between 1 and 120. The first levels are to warm you up, the higher ones if you're looking for a real head-scratcher. The grid awaits you.
Place the starting digits
Place the digits indicated by the challenge on the board and read the conditions: which sums must add up, which spaces remain to be filled. The starting point is clear — the path is not.
Fit them in and do the math
You try to fit the remaining digits. One fits perfectly, but the sum doesn't add up. You move another and the fit breaks. You realize that space and calculation must be solved together.
The "aha!" moment
You deduce which pair of digits can make up that sum, and suddenly everything else falls into place. The last pieces find their spot as if they were just waiting for you.
The sums add up
The last digit slides into place, the grid is full, and every sum matches. You close the lid with a smile — and your eye is already on the next challenge.
How to play
Four steps for each challenge
You learn in a minute and play for hours. No rules to remember: just logic, a bit of calculation, and patience.

Frequently Asked Questions
IQ Digits FAQ
Is it just a math exercise disguised as a game?
No. IQ Digits is first and foremost a fitting puzzle: numbers add a layer of deduction, but you don't have to do complicated calculations. You need to think about which pieces fit where and which sums they can compose — more spatial logic than arithmetic. Math is present, but it's the pretext for the puzzle, not a chore.
Recommended for ages 7+: isn't it too childish for an adult?
No. The minimum age only indicates when one can start to understand it, not its upper limit. The first levels are simple, but the expert challenges puzzle anyone, adults included. It's a puzzle that grows with you: easy to pick up, far from easy to finish.
Do you need to be good at math to play?
Just knowing how to add is enough. The core of the game is understanding how to fit the digits and which combinations yield the correct sum: it's mainly logic and deduction. That's why it works so well with children too, who train their numbers without realizing it.
How difficult are the challenges?
They range from easy, almost immediate, to expert levels that require reasoning and several attempts. The 120 challenges increase gradually: you grow with the game and each level prepares you for the next. Suitable for those who want to relax and those looking for a real brain-teaser.
Is it suitable for travel?
It was made for this. The case is compact, has a transparent lid, and the pieces stay in place, so you can play it on a train, plane, or at a cafe while waiting. A single challenge takes only a few minutes: ideal for filling downtime.
Do I need to know English to play?
No. The challenges are visual diagrams with numbers: you look at the pattern, place the digits, and play. There's no text to read during the game, so language is not a barrier.
