PoliGuard unblocked is a free tower defense game with no last level, and everything on screen is made of bright neon shapes. Red invaders travel down a winding orange path on a black grid, and you hold them back with towers shaped like stars, squares, pentagons, diamonds, hexagons and circles. The towers fire on their own, so your choices are what to build, where to put it and which upgrades to buy.
The Goal and the First Wave
You start with 100 coins and ten lives. Enemies enter from the left edge, follow the road through eight sharp bends and leave on the right. Every enemy that reaches the exit costs one life, and the run ends when lives hit zero.
To build, pick a tower from the panel on the left or press a number key from 1 to 7, then click an open square away from the road. The placement outline turns green when the spot works and red when it does not. Press Escape to cancel a selection.
Wave one sends five enemies, about one every three quarters of a second. When a wave is cleared, a five-second countdown runs before the next one starts, which is your window to build and upgrade.
How the Waves Grow
The math behind each wave is simple and steady. Enemy health is 30 plus 10 for every wave number, so a wave-1 enemy has 40 health and a wave-10 enemy has 130. Their speed also rises a little every wave, and they get slightly larger.
The crowd grows too. Each new wave has five enemies plus one and a half per wave number, so wave 2 has 8, and wave 10 has 20. Rewards keep pace: a kill pays 10 coins plus 2 per wave and adds 50 points plus 10 per wave. A wave-10 kill is worth 30 coins, which is why the late game lets you afford big upgrades.
The Seven PoliGuard Towers
Each tower has its own price, shape and job. Fire speed is listed as time between shots.
- Basic (50 coins): a star with 20 damage and one shot per second. Cheap and solid for the opening.
- Fast (75): a square that fires twice a second but hits for only 15 and has the shortest reach.
- Strong (100): a pentagon dealing 40 damage every 1.5 seconds.
- Sniper (150): a diamond with 60 damage and by far the longest range, firing once every 2 seconds.
- Explosive (120): a hexagon whose 25-damage blast also hurts nearby enemies. Ones close to the center take more, and the edge still takes 30%.
- Ice (90): a square with weak hits that cut an enemy’s speed in half for three seconds.
- Poison (110): a circle that adds 3 damage per second for four seconds after each hit.
Upgrades and Selling
Click the small “i” on a tower card to open its upgrade panel. Every type can buy damage, range and fire speed. Damage adds 5 per level, or 10 for Strong and 15 for Sniper. Range adds 20, and fire speed trims the gap between shots down to a set limit.
Prices climb with each level. The first damage upgrade costs 50 coins, then 75, then 100. Range starts at 40 and fire speed at 60. Explosive, Ice and Poison have a fourth upgrade starting at 80 coins that widens the blast, deepens the slow or adds a point of poison damage and a second of duration.
To sell, click the Remove button or press Delete, then click a tower. You get back 70% of its build price.
PoliGuard Strategy That Holds the Line
- Spend your first 100 coins on two Basic Towers. That is exactly what you can afford, and they handle the early waves well.
- Use the corners. A tower placed inside a bend can shoot enemies on both sides of the turn.
- Pick two or three favorite types. Because upgrades cover every tower of a type, focusing your coins makes each purchase count many times over.
- Combine Ice with damage. Slowed enemies stay in range longer, so neighboring towers land more shots.
- Point Snipers at the toughest target. Right-click a tower to choose closest, strongest or weakest, and set Snipers to strongest.
- Save Explosive Towers for later. Bigger crowds bunch up in later waves, which is when splash damage shines.
Mistakes New Players Make
The biggest one is spreading coins across all seven towers. One of each type leaves every upgrade weak. Another is building far from the road, where only part of a tower’s circle covers the path. Hover over a tower to see its range ring before you commit.
Players also forget about the pause button. Pausing freezes enemies while you read cards and buy upgrades, and it shows speed buttons for 0.5x, 1x and 2x. Use 2x during easy waves and drop back to 1x when the road fills up.
Playing at School
PoliGuard needs a mouse and keyboard, so it works best on a laptop or Chromebook with a full-size screen. You can zoom with the scroll wheel and drag to pan if the map feels cramped. It suits a longer break, since a good run can last many waves, but you can pause at any moment when the bell rings.
