Logic Trainer "Restore Logical Order"

I came up with this trainer in the summer of 2025, and I find it quite effective for developing logical thinking. In it, you need to establish the correct sequence of icons, taking into account the given conditions of the problem, where one icon is larger than another, or there are more of one icon than others (whichever way is easier for you to perceive the task), with animal images acting as icons. The essence is simple - if one icon is larger than another, it must be placed to the right of it. You need to consider several conditions and restore the order of arrangement for five to nine icons in the problem, depending on the chosen difficulty. Try to solve the problem yourself; it's not difficult, but engaging and beneficial for your logical thinking.

Game-Trainer for Logic and Thinking "2048"

This trainer, invented by Gabriele Cirulli, can be not only an entertaining pastime but also a full-fledged logic trainer, as you need to plan your moves considering possible interferences, which are tiles with the number 4 that randomly appear in limited numbers instead of the number 2. Tiles stack on top of each other when flipped in the direction of fall, forming a number twice as large if they have the same value. The goal of the game is to sequentially collect a tile with a value of 2048. It is not infinitely difficult, but not easy either, because if the game board is completely filled with tiles, you lose as you will have no more moves.

Game-Trainer "Ultimate Tic-Tac-Toe"

You are probably familiar with the game "Tic-Tac-Toe"; many people played it in childhood with friends or classmates, or within their family. Unlike ordinary "Tic-Tac-Toe," Ultimate Tic-Tac-Toe offers you to play on a large board consisting of nine small, standard Tic-Tac-Toe boards, where to win you need to achieve a series of wins on the small boards of the large game board so that you line up three wins in a row horizontally, vertically, or diagonally. It is important that you direct your opponent to the game board indicated by your move in the small game board. And remember, sometimes a loss on one small board can lead to victory on the large one; direct your opponent wisely.

Logic Game-Trainer "Master Packer".

At first glance, it might not seem very obvious to you that this trainer develops logic - just know, place blocks on the game board and that's it. However, in practice, it turns out to be not so simple, especially in some particularly complex cases. The fact is that when assembling the game board, it often turns out that you somewhere violated the order and placed a piece not in its place, especially if the generation created a combination of pieces that can be placed on the game board in a limited number of ways. And it is precisely one of such possible sequences that you need to find, and logical thinking is a necessary condition for this.

Game-Trainer "Sudoku Online".

The game Sudoku has gained particular popularity among people who enjoy solving puzzles. Here, you need to place numbers on the game board in such a way that the vertical and horizontal rows of the large 9x9 game board contain numbers from 1 to 9 without repetition. Additionally, each small 3x3 field within the large board must also contain only the sequence of numbers from 1 to 9 without repetition. This creates the necessity of placing numbers on the game board in the only possible way, meaning the puzzle has a unique solution, which requires a good level of logical thinking and attention to place them in a relatively short time.

Engaging Einstein Riddles

Creating a universal generator for Einstein riddles took me quite some time this year, but I think I managed to create working code that generates hints with a single correct solution, allowing for the creation of Einstein riddles from the simplest to the most complex. This logic trainer is a set of hints, usually from 15 to 20 hints, with which you must determine the arrangement of five types of elements in five houses. Without applying logical thinking, and in complex versions of the puzzle without some trial and error, solving Einstein riddles here seems very difficult. However, with our universal Einstein riddle solver, sequentially eliminating unnecessary options from the table, you will find the solution with greater ease.

Logic and Spatial Thinking Trainer "Ballistics".

Here, you will briefly play the role of an artilleryman who needs to hit targets that are in direct line of sight but behind an obstacle, making it necessary to choose a ballistic trajectory with a high-arcing shot over the top. You will be given a certain number of types of projectiles, several of each type. Different types of projectiles have different power, allowing you to launch a projectile over different distances, meaning each time after the first shot with one type of projectile, you need to calculate the projectile's flight trajectory so that it reaches the target. Such a task will require logic and spatial thinking from you to hit as many targets as possible with a smaller number of fired projectiles.
