Playing Slither.io

1
Use the mouse cursor to control your slither. Your slither will move in the direction of the on-screen mouse cursor. On PC and Mac, simply use the mouse to control the direction your slither moves. On smartphones and tablets, place your thumb on the left side of the screen and drag it in the direction you want your slither to move. You will see the arrow icon move and point in the direction your slither is moving.
- You can see where you are in the play area using the mini-map in the lower-right corner.
2
Eat the glowing orbs. You will grow by 1 ball length for each glowing orb you eat. Eat as many glowing orbs as you can to get as long as you can.
3
Activate speed boost. On PC or Mac, simply click and hold any one of the mouse buttons to activate speed boosts. On smartphones and tablets, tap and hold the arrow icon to the right to activate speed boosts. While using speed boosts, your slither will lose 1 ball length for every second you don't eat.
- On smartphones and tablets, you can tap Move controls at the top of the screen to move the speed boost button from the left to right side.
4
Avoid other players. While playing Slither.io, you will run into other player's slithers. If the head of your slither runs into another player's slither, you will lose the game and your slither becomes glowing orbs for other slithers to eat. Use speed boosts to try to get away from other players.
- There is no penalty for running into the body of your own slither.
5
Try to get other players to run into you. The longer you get, the harder you are for other players to avoid. The easiest way to try to get other players to run into you is to form a circle around them to trap them. Then they can't escape. Also, be careful if other snakes try to do that to you. In some lucky cases, you let the head of the other snake crash into you, and then you are surrounded by food orbs.
- Bigger snakes may also try to trap you. Try to stay away from big snakes. If they enclose you in their trap, they are most likely to eat you when you are destroyed. Be careful!
6
Try to get on the leaderboard. The top ten players on your server are listed in the upper-right corner. The longer you last, the bigger your slither gets and the more points you get. If you last long enough, you will get to see your name on the leader board in the upper-right corner.
- If you are particularly proud of your score, you can click Share on Facebook or Share on Twitter to brag about your score on social media when you lose.

Question

Is it best to use a mouse for it or the arrow keys?

It is best to use a mouse because it gives you more control. But you could use arrow keys if you are comfortable with them.
