However, there are also games that can actually boost your mental health and train your intelligence – sounds good?

Without further ado, let’s dive into the list of some of the best games that make you think and improve your puzzle-solving abilities.


Developer:Wube Software

The first game on the list is none other than Factorio – a game about creating the most efficient factory possible.

Factorio is a sandbox factory simulation game with a simple goal – to make a factory that will create all sorts of goods and semi-products to ultimately make and launch a rocket and leave the inhospitable alien planet, on which you accidentally crashed. The game strikes a balance between being accessible to inexperienced players and providing a virtually unlimited challenge for the veterans. That’s because, in the long run, it doesn’t matter if your factory will work as efficiently as possible or not – if you don’t want to spend time and effort to optimize everything to the limits, you will still be able to reach the final goal, it will just take you some more time.

Key features
  • A fun factory simulation that revolves around creating a factory and manufacturing all sorts of goods
  • Procedurally generated, customizable worlds that ensure that no two playthroughs are exactly the same
  • A solid management game – research and create new types of items, manage power grids, build mines and refineries, and transport stuff on conveyor belts or trains
  • Multiplayer mode that can support as many as over 200 people playing simultaneously



Have you ever wanted to program your very own team of robots and send them to battle against teams programmed by other players? If so, this is the game for you.

Gladiabots is a programming video game, where your objective is to create a set of instructions for your robots to follow in order to defeat the opposing team. There are 3 different online game modes available, and each one requires a different strategy – one mode, for example, is about simply killing the enemy robots before they kill your team, but there is also a mode that requires capturing randomly generated orbs and taking them back to your base to earn points. Programming the robots is much easier than you think – there is no single line of code needed to be manually written. Instead, you will have to use all sorts of customizable instruction blocks. Come up with clever solutions and surprise your opponents – the possibilities are endless.

Key features
  • An addictive strategy game about programming robots and sending them to battle
  • Virtually infinite possibilities – design your own AI to handle all scenarios and difficult edge cases
  • A comprehensive single-player campaign that teaches everything you need to know in a newbie-friendly fashion
  • 3 different online game modes, 4 robot classes with customizable skins, and a simple, intuitive interface

The Witness

Developer:Thekla, Inc

The Witness was a very refreshing experience – it’s an ambitious project that redefined the puzzle genre in video games.

The Witness is a 3D puzzle game that consists of hundreds of unique environmental puzzles that you need to solve in order to progress further and unlock even more content. The puzzles start rather simple – all you need to do is to draw a line that connects two points. Things start to get funky once you complete later stages and realize that these puzzles can be literally anywhere around you, not just on the designated puzzle boards – you need to be well aware of your surroundings, as this can be crucial to finding not only a solution but the puzzle itself. Sometimes you need to think out of the box or look at things from a different perspective. This is also where you truly start to appreciate the effort that was put into creating this beautiful masterpiece.

Key features
  • An addictive puzzle game with an open-world environment and exploration
  • Hundreds of increasingly difficult puzzles to solve with new rules being added gradually as you progress further
  • Numerous hidden challenges for those who are curious and smart enough to find them
  • A relaxing atmosphere with beautiful visuals full of vivid colors

Portal 2


This game probably doesn’t need an introduction – it’s one of those iconic titles that ring a bell even if someone doesn’t play video games too often.

Portal 2 is a puzzle-platform game, where you need to use your portal gun to navigate through increasingly difficult test chambers. You can fire two types of portals – orange and blue. Only one portal of each color can exist at any given time, and whatever enters one portal will exit from the other. You need to smartly utilize this fact to find a way to escape the room and get to the exit, where a new puzzle awaits. Later during the game, new gameplay mechanics are introduced to give you even more advanced puzzles to solve – it’s a true IQ test for the most intelligent individuals. The game also comes with a super fun multiplayer co-op mode with a completely new set of challenges designed exclusively to be solved by two players working together. If you have someone to play with, definitely give co-op mode a go.

Key features
  • An iconic puzzle game with a casual-friendly atmosphere and a good dose of humor
  • Increasingly difficult environmental puzzles that come with various cognitive benefits for your brain
  • Easy to learn but gets more complex as new gameplay mechanics are introduced in later stages
  • A solid number of challenges designed to be played exclusively in co-op multiplayer

Keep Talking and Nobody Explodes

Developer:Steel Crate Games

This is an interesting game due to how unique it is. Although you can play it alone, it’s clearly meant to be played together with at least one another player – keep that in mind before you decide to give it a go.

Keep Talking and Nobody Explodes is a video game focused on the process of defusing a bomb. One player is tasked with describing what he sees, while the rest must read through the manual to find the solution and instruct the first player on what to do next – which button to press, which cable to cut, and so on. The game requires good teamwork and communication skills, but it’s super fun once you get the hang of it. The puzzles that appear on the bomb and need to be solved are randomized each playthrough, which means that you can’t simply memorize everything unless you spend hours upon hours trying to do so. It could serve as a nice hardcore challenge to improve memory, though, so maybe it’s not an entirely bad idea to give a solo run without a manual a try.

Key features
  • An addictive puzzle game that can serve as a perfect party title or a challenge for lone wolves
  • Procedurally generated challenges that ensure that no two playthroughs are exactly the same
  • Complex puzzles that purposefully make communication harder by changing the meaning of certain words or requiring players to describe certain symbols
  • Only the bomb defuser needs to own a copy of the game – the rest can download the manual for free

Scribblenauts Unlimited

Genre:Arcade & Platform
Developer:5th Cell

On a more unique side of the spectrum of video games designed to try a brain, we’ve got Scribblenauts Unlimited – a game, where you have to use your imagination and creativity to solve the puzzles.

In Scribblenauts, you have a special ability that allows you to create objects out of thin air by simply typing what you want to get. Do you want a big red apple? Type that in, and you will get it. Do you want a fast flying horse? It also shouldn’t be a problem. The game features tons of different puzzles, and to solve them you need to figure out yourself what object will be of most use. The game won’t tell you what you need, and it’s up to you to come up with a solution. With that being said, most puzzles can be solved in a number of different ways, which results in non-linear gameplay that encourages players to experiment with stuff.

Key features
  • A puzzle sandbox game that puts emphasis on the use of the player’s own imagination
  • An ability to create almost any possible object you can think of by simply typing a combination of nouns and adjectives
