A game is smart if it is both fun and
challanging, and thus exercises the players brain.
We have several smart-games!
Sudoku is a typical smart-game! We have 5 levels of
difficulty. From Zero Sudokus, for very young children, to
Deep Thought Sudokus.
Our powerful computer has tested millions of
sudokus, and examined what "rules" one must apply to solve them!
Our objective has been to pinpoint both simple and difficult sudokus
that are extra fun to solve.
Please, visit our sudoku page for more info!
This is the Classic Game also known as Connect Four, Four in
In this game, you and the
AI (artificial intelligence) take turn to place bricks in bottom up
order on a game board. The goal is to line up 4 bricks before
the opponent does it! Please visit our i4Row page.
antiJam is our best smart-game.
Novel, fun and clever. Easy to learn, impossible to master! Try!
The Solver is really not a game, but an AI Solver to
the Mastermind game from the 70:th!
This is the classic memory game,
now called remember cards on 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 with the built in robots!
Memory, Recall Card
Our Memory game is also available on Apple TV! Recall Card/Memory-Game is the classic memory for TvOS!
There are several ways in which a computer can help a student to truly understand a
topic! One approach is to let an artificially intelligent tutor present
a step-by-step solution to a problem that the student has made up! A
different approach is to let the student play with a simulator. We use
both these approaches in our smart educational Apps!
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.
This Percentage Template Tool will help the user to answer questions such as:
If 7% of X is 250, then what is X?
Smart learning Apps targeting higher education in electrical engineering and computer
The learning tool DC Sim can simulate an electric circuit with multiple batteries, current generators, on/off-switches and resistors.
This is a fun tool for those of us who knows the laws of Kirchhoff et al. As the tool is quite playful, we believe it will boost anyones curiosity and let him or her mature as an electrical engineer.
The Sampling Theorem
The learning tool aliasing is targeting
advanced studies of the Shannon/Nyquist Sampling Theorem. This is
advanced math! The App is
completely free, but please do
not download it unless you are already familiar with the theorem and
like to acquire a deeper understanding!
This is an expert tool for people interested in audio.
If you like to test e.g. your headphones,
AirPlay enabled speakers, or maybe some device you are building your self,
then this signal generator may be of use.
We call it signalator.
