Agar.io

About: Chasing cell game.

Agar.io is the first ever io game that was launched in 2015 and was developed by a nineteen-year-old kid Matheus Valadares. You can play it for free on your browser or can download its app.

It is a simple yet challenging game where there are several cells on the board and you are one of them. You have to rescue yourself from the bigger cells and need to get bigger by eating other small cells.

There are five game modes you can choose from: Free-for-all (FFA), Battle Royale, Teams, Experimental, and Party Mode. The mechanics are fairly simple: you just need to move the mouse cursor in the direction where you want your cell to move.

How to play:

This is a simple game where you need to eat the smaller cells to become a big cell and rescue yourself from the bigger ones. You can also split into smaller cells at the correct time to rescue yourself from being eaten up by the bigger cells by pressing the spacebar.

As you grow bigger by eating tiny cells, your speed would get slow, now it would be different for you to move quickly. There is a big green virus cell that can split your cell into various small cells. You can hide yourself behind the big green virus cell from the bigger cells coming your way.

Controls: If you play the game on your desktop then you need these controls-

• Mouse the cursor to move your blob.
• Space bar for splitting the cell.
• W key for ejecting mass.

Developer: A nineteen-year-old Brazilian kid Matheus Valadares.

Tip for high-score:

• You can hide behind the big green virus cells from the bigger cells that are chasing you as the virus cell is harmful to the big cells, not the smaller ones.
• Press the W key 7 times towards the virus-cell to make it split in the direction where the larger cell is placed.
• You can split yourself to consume small cells and become a bigger cell easily.
• You can team up with other players to knock out others on the board collectively.

Our Review: Agar.io is a simple game with fairly simple mechanics that anyone of any age can play easily. It is an online multiplayer game, lightweight, that can be played on any low-range device that does not require a lot of resources.

It also doesn’t have timers and time bars, so you can play at your own pace. The game relies on the internet connection, you can not play it offline.

Flappyroyale.io

About: Battle Royale-style game.

Flappyroyale.io is a simple arcade game where you as a flappy bird need to fly forward rescuing yourself from pipes or obstacles coming your way. There are shadows of other birds that are your competitors but could not come your way.

You can just see them trying to move forward as you go. At the end, the chart will present the total number of obstacles you have gone through. You are given 10 lives per day. You can reach as high a score as possible using these 10 lives. Once the 10 lives are over, you can play again the next day.

They also allow you to customize your character, including its body and accessories. It is a game just like the Flappy Bird with new dimensions, all thanks to the competition.

How to play:

You need to fly your bird all through the pipe word with many other obstacles coming your way by using the right click of your computer mouse or by tapping on your screen if you are playing on your mobile.

You need to be very cautious, as a slight wrong move can take your life. It includes 99 unique stages where you can challenge yourself to be very patient.

Developer: Long Experience engineer- Orta Therox.

Tip for high-score:

To stay in the game for the maximum amount of time, here are some tips:

• You need to find the right rhythm so you should be slow.
• Let yourself fall to make your way into the pipe coming your way.
• A tablet is a wonderful option to play this game. It makes you easy in the rhythm.
• You need to be very calm in the entire game.
• Try to play the game in an area with no distractions as it demands your full concentration.
• Change your flap rhythm as and when required.

Our Review: Flappyroyale.io is an interesting as well as nostalgic game similar to the Flappy Bird. It gives the gamers a good challenging experience where they need to be very focused as a slight eye move can become the reason for their defeat.

It is simple, stupid, and very hard to play. The controls are also very simple; you don’t need to use many keys for the gameplay, you just need to keep tapping on the screen to make your bird fly the right way.
