Polygons are naturally-spawning shapes that dot the arena. They serve as regularly harvested naturally occurring score (only in some game modes) and XP resources, and are an essential feature of the game.
Unlike tanks, they do not have their own weapons and can only use their low Body Damage to defend themselves just like the Smasher, though both the tank and the Polygon will take damage. Most Polygons, albeit slow, are not completely stationary, as they will slowly drift about. Crashers that are looking for a target are immobile until a target appears to crash into. They may be pushed by tanks, Ammunition, Arena Closers, Protectors, some Bosses and other Polygons such as Crashers. Crashers will not push each other, however.
The number of Polygons able to spawn in an arena is directly related to how many players are currently occupying the arena. In Sandbox mode, a single player yields twelve polygon spawns, but it is unknown what the exact ratio actually is since more players might not yield an exact 1:1 ratio. In Team DM mode with less than ten players (meaning the Leaderboard isn’t even fully filled), Polygons are very scarce to come across since the Polygons may spawn anywhere inside the arena (except in spawn areas), and very few of them spawn due to a low amount of players. Most of the time when this uncommon situation occurs, the Pentagon Nest is literally barren of all Polygons (since Pentagons have a lower spawn rate in general, even in the Nest), and the corners of the arena have basically what little of all the remaining Polygons clustered together. This also explains why Pentagons are so rare in their own nest (the area blocks non-Pentagons or non-Crashers from spawning yet has a regular Crasher and Pentagon spawn rate).
Polygons will regenerate health if they are left unharmed for at least thirty seconds, and will spawn out of other Polygons if left alone long enough, harmlessly repelling each other as they divide. A player will gain experience from any Polygon that they destroy so long as they deal the final blow to that Polygon.
Most Polygons have no AI and only move in fixed circular paths. However, some Polygons are AI controlled. Crashers, for instance, will chase down the player to defend the Pentagon Nest if the player is within their attack range.
On rare occasions, a player may stumble across a green version of a Polygon. These variations have a much higher health pool and award ten to a hundred times the amount of XP to the tank that gets the final blow on one, although their spawn rate is almost nonexistent - only very few have been caught on videos.
- Main article: Square
The Square is the weakest and most common type of Polygon in the game and as such gives little experience, but is useful for Tier One players as a way to gain experience. It only grants ten XP in FFA, 2 Teams and 4 Teams and since Domination has a multiplier of two, it effectively grants twenty XP in that mode. Necromancers can convert yellow Squares into their own Drones by touching them, either with themselves or with their Drones. The Square has a very rare green variation called the Green Square.
- Main article: Green Square
The Green Square is a very rare Polygon. It is similar in appearance to the standard Yellow Square but is colored a bright lime green color. When killed, it drops 1,000 XP points in FFA, 2 Teams and 4 Teams style modes. Like a basic Square, it can be “infected” by the Necromancer. It has more health than normal square. If you destroy one, you will get the Shiny! Achievement.
- Main article: Triangle
The Triangle is stronger than the Square, but weaker than the Blue and Alpha Pentagons, making it the second weakest Polygon. Currently, it drops twenty five experience points in all Game Modes, but in Domination the multiplier is double, so though only twenty five XP are gained, fifty are effectively rewarded.
- Main article: Green Triangle
The Green Triangle is similar to the regular Triangle but has a bright green color and is ten times tougher to destroy than the normal one. It drops 2,500 XP in FFA, 2 Teams, and 4 Teams. If you destroy one, you will get the Shiny! Achievement.
- Main article: Pentagon
The Pentagon is the second strongest Polygon among the regular ones, and is regarded as the simplest and best source for experience. Tier One tanks will benefit greatly if the opportunity arises to destroy one. It currently grants 130 XP in FFA, 2 Teams, and 4 Teams modes, and in Domination the XP multiplier is double, so it effectively awards 260 XP. Like the Triangle and Square, it also has a rare green variant called the Green Pentagon, as well as an unconfirmed (and probably much rarer) orange variant, called the Orange Pentagon.
- Main article: Green Pentagon
The Green Pentagon is similar to a Blue Pentagon. It has around five times the health of a normal pentagon, and grants 13,000 XP to whomever lands the killing blow. If you destroy one, you will get the Shiny! Achievement.
The Pentagon Nest
- Main article: The Pentagon Nest
The Pentagon Nest is an area located in the center of the arena. It has a high concentration of Blue Pentagons and Alpha Pentagons. Large and small Pink Triangles - known as Crashers - only exist here. They will target players entering the area and will continue to chase them down outside it.
- Main article: Alpha Pentagon
The Alpha Pentagon is the strongest Polygon in the game. It takes many hits to destroy even for the strongest players. It is also the largest Polygon in the game. Killing one rewards 3,000 experience, which makes it the largest and most coveted source of experience in the game. Alpha Pentagons only spawn in the Pentagon Nest.
One can easily tell an Alpha Pentagon from a normal Pentagon by the thickness of its outline; an Alpha Pentagon’s outline is much thinner, compared to its total body size. Also, regular pentagons are dwarfed by its massive size making it stand out in the crowd.
The Alpha Pentagon is also the only Polygon that has not been confirmed to exist in any color other than normal blue; some videos showcasing green or orange Alpha Pentagons exist but have been proved fake.
- Main article: Crashers
The Crashers often come in swarms and will seek players in range, taking on the form of a Pink Triangle. They spawn in the Pentagon Nest but will continue to follow the player (even into their Base) until either the Crasher is destroyed, or the player. Becoming invisible is also a viable tactic in avoiding them. However, once they have spotted a player they will target it even if they’ve turned invisible. They have two sizes: Small and Large. The small Crasher has the same amount of health as the Yellow Square has. The Large Crasher has the health of the Red Triangle. Large Crashers give twenty five EXP, and Small Crashers grant fifteen EXP. They have a field of view slightly lower than the Assassin’s.
- The points given by the Polygons don’t decrease as you get bigger, contrary to many people’s belief. It just takes more points to level up to higher levels.
- In the very early versions of Diep.io, Polygons didn’t exist, forcing you to immediately start fighting others at level one, making the game practically impossible for new players.
- Polygons have a slightly different amount of Body Damage between each other but the default Body Damage of tanks is the highest.
- All Polygon Bosses, excluding Fallen ones, have a body identical to a Polygon:
- People have thought that a much rarer version of the Pentagon existed. This is the Orange Pentagon. There have been no confirmed videos of the Orange Pentagon, if it does exist.
