Smart Games

Smart games are also known as intelligames. They are fun and challanging and make the player smarter. We have several smart games!

Sudokus


We master the subject of producing sudokus. We have defined 5 levels of difficulty, from Zero Sudokus, for very young children (age 6), to Deep Thought Sudokus, for true experts.

By using computers, we have scrutinized tons of sudokus and examined what kind of "rules" one must apply to solve them! Our objective have been to find sudokus that are very fun to solve!

To find out which level suits you, try our free Sudoku Mix. It contains 1 free sudoku at each level of difficulty.

If you like sudokus, you should definitely visit our sudoku page for more info!

Hit Chess

Hit Chess a.k.a reverse chess, anti chess, chicken chess. You play with chess pieces on a chess board, and move the pieces as in chess, but your aim should be to get rid of all your pieces. That is to say, you should let your opponent take them! But when you can take one piece from your opponent you must do that!

i4Row

This is the Classic Game that is also known as Connect Four, Four in Line, etc. In this game, you and the AI (artificial intelligence) take turn to place bricks in a bottom up order on a game board. The goal is to line up 4 bricks before the opponent does it! Our AI is smart, and our UX is superb. Please visit our i4Row page for more information!

antiJam

antiJam is our best smart-game so far. Novel, fun and clever. Easy to learn, impossible to master! Try it!

Mastermind Solver

This App is really not a game, but an AI Solver to the Mastermind game from the 70:th! -Spooky, it reads your mind!

Mastermind AI

Meet the mastermind! This App has three game modes that include both the mastermind game and the spooky solver. Visit Mastermind AI!

Remember Cards

This is the classic memory game, now called remember cards, for iOS. You can download the App for free, and also play the small game board for free! The App has no adds! The App's user interface is easy to understand (and it can therefore be played by young kids)! It is a family game, but if you like to play it alone you can play against the built in robots!

Memory, Recall Card

A somewhat older version of our Memory game is also available on Apple TV!

Educational Apps

There are at least two ways in which a computer can help a student to understand a topic: 1) Let an artificially intelligent tutor present a step-by-step solution to a problem that the student has made up! 2) Let the student play with a simulator. We use both these approaches in our smart learning Apps!

Some Apps, but not all, are targeting higher education in computer science/electrical engineering.

Fractions Learning Calculator

This Fractions Learning Calculator will help the user to understand how to calculate with fractions. The user presents a math-problem, and can then watch the AI-based tutor solve that problem step by step.
