From Battleship to Chess, board games are old, but they are still popular today. Anyone who has never played a game of Monopoly, Monopoly, Game of Life or even the simplest card games definitely didn't have a childhood.

But if you haven't had the privilege of playing any of them yet or if you have already played but can't get your friends together for a game due to social isolation, don't despair. There are several free board games available on Android and iOS smartphones. Check out the list I've prepared with the 5 best games of the genre for you to download on your phone.

1. Einstein's Riddle

First on the list, I decided to put a game that is not so well-known, but is worth checking out. In Einstein's Riddle, you need to put each item in its proper place using logic. To do this, the game gives you a series of hints so that you can put each item in the right place (check out the video above that illustrates it well). For example: The Englishman wears a baseball cap. The American likes juice. The owner of the Fox doesn't drink milk.

The game's difficulty ranges from easy (3×4 board) to insane (16×9 board). There are even daily challenges for you to solve. Click here to install Einstein's Riddle on Android or here to download on iOS.

2. ONE!

Despite being old, UNO gained popularity in the 2000s and is still a huge hit today. The mobile game developed by Mattel163 offers different modes for playing alone or with other players online. In addition to finding modes with classic rules in quick solo free-for-all games, you can make friends (or ruin them) with personalized rules in 2v2 games. So, in 2v2 games, you have access to your partner's cards to define the best play.

There are also in-game events that put you in rankings among your friends, regionally and globally. You can download UNO! on your Android by clicking here, or here to install it on your iOS device.

3. Chess – Clash of Kings

The fourth place on the list is for those who know how to play Chess. Or even for those who, like me, are aspiring to play. With more than 10 difficulty levels, Chess – Clash of Kings also offers tips on moves during the game. In the game, you can also complete challenges and puzzles that can help improve your level and notion of movement during matches.

In Chess – Clash of Kings, in addition to playing against the computer, you can play games with friends or other random users from different parts of the world. Depending on the type of game you choose, you receive rewards in coins to spend in the game (customized boards and new avatars).

4. Sea Battle 2

Sea Battle is a game developed by Byril that has offline and online modes to play with friends or players from other parts of the world. For those who have never played a sea battle, it's simple: just distribute your ships on a table that goes from A to J (vertically) and 1 to 10 (horizontally). So, without knowing where the enemy ships are located, you must try to hit the enemy vessels to destroy them little by little.

You can choose to play against bots, real players, and even participate in tournaments to earn rewards in coins, which can be spent within the game. This way, you can use the coins to build places in your city and purchase other items. During the game, you can customize your character with any color you want. By the way, it is worth mentioning that the game has a very cool aesthetic in the form of pen drawings.

Install Sea Battle 2 on your Android ou iOS. The first version (Sea Battle) is also available on both platforms.

5. Ludo Club

The popular board game Ludo is also available for free on smartphones. The game developed by Moonfrog allows players to play offline and online. In offline mode, you can play against the computer or someone nearby (on the same device). In online mode, you can challenge friends or play against other people in 2v2 or free-for-all matches.

To play, you must choose your color and enter the game. Players can only remove the pins from the house when they roll a 6 on the dice. From then on, just move all your pieces according to the number on the dice to reach the end of the board. During the journey, you can eat the pieces of the other 3 players to hinder them. The first player to put all their pieces in the right place wins. Download Ludo Club through Play Store or App Store.

We always remind you that even though they are free, the games above have optional in-app purchases. Check out our other lists as well: 5 puzzle games to overcome boredom on Android, Top 7 best FPS games for mobile e Top 5 Crossword Games for Android.
