Square

The Yellow Square is the weakest and the most common polygon in Diep.io. It can be identified by its bright yellow color and its square shape. When killed, it gives 10 points. With no upgrades, it takes 2 shots or bullets to defeat it. If you crash into it, you (and it) will take some damage. A Necromancer can make it into one of its minions by crashing into it. Do not mix the ones untouched by the Necromancer with the Necromancer’s minions, which are darker colored.

Trivia

 * With one point in bullet damage, you can defeat it in one hit. At one body damage, you can destroy it by touching it, without the extra body damage. It is also possible to kill it by ramming into its center.
 * Putting one point into bullet penetration will allow you to hit the square multiple times, killing it with one shot. This may be a better option to gain additional EXP per square.
