Is Pokémon Tower Defense unblocked at school?

Yes. Pokémon Tower Defense runs in a normal browser tab from pokemontowerdefense.org with nothing to install, so it plays on most school Chromebooks. If a network filter blocks the site, only that network's administrator can change it.

How do you play Pokémon Tower Defense?

Choose a starter in Oak's Lab, then drag your Pokémon from the party bar onto the grey circles beside the path. They attack wild Pokémon that walk toward your rare candies. Defeats pay pokédollars for Level Up; a wild Pokémon on red health can be caught by dragging the Poké Ball onto it.

Is this the original Pokémon Tower Defense?

No. The original was a Flash game by Sam and Dan Games from 2011. This is a fan-made remake in HTML5 by jeffbrin that recreates the first chapter — Oak's Lab to Brock's Gym — and it is the same game the old version of this site showed.

Which starter should I pick?

For the last level, Brock's Rock-type gym, Squirtle (Water) or Bulbasaur (Grass) is easiest. Charmander is weak to Rock, so with it you will want to catch a second type along the way.

How do I catch Pokémon?

Attack a wild Pokémon until its health bar turns red, then drag the Poké Ball from the bottom-right corner over it and let go. You start with one ball and get more for clearing a level the first time.

Does it save my progress?

Yes, in your browser's local storage: your name, party, box, pokédollars, Poké Balls and the furthest level reached. Clearing site data or switching browsers starts over.

Pokémon Tower Defense Unblocked

This is Pokémon Tower Defense unblocked: a fan remake of the Flash game's first chapter runs above, served from pokemontowerdefense.org itself, so it plays in an ordinary browser tab on a school Chromebook or laptop — free, with no download and no account.

Pokémon Tower Defense: rare candies, a Poké Ball and a road to Pewter City

Pokémon Tower Defense started in 2011 as a Flash game by Sam and Dan Games, and it was one of the most-played games on school computers until Flash was switched off. What runs above is not that file. It is a fan remake written in TypeScript by a developer publishing on GitHub as jeffbrin, and it rebuilds the opening chapter of the original in plain browser code: the same idea, the same pixel-art Pokémon, the same Kanto road from Professor Oak's lab to the Pewter City gym. This is the same build the old version of this site had on its front page, now served from pokemontowerdefense.org itself.

The game opens with a title screen full of sprites, asks your name, and hands you over to Professor Oak. He introduces Nidoran, then lines up the three Kanto starters — the Mighty Squirtle, the Fierce Bulbasaur and the Scorching Hot Charmander. Clicking one opens its Pokédex card: a description, its type, and the types it is weak to. Pick one and it becomes the first member of a six-slot party that sits along the bottom of the screen.

Then the tower defense begins. Each level is a small map with grey circles beside the path. Wild Pokémon walk in and head for your rare candies; your Pokémon, dragged onto the circles, attack anything in reach with their real moves. Every wild Pokémon you defeat pays pokédollars and gives experience to the Pokémon that fought it. When a wild one's health bar turns red you can catch it instead — drag the Poké Ball from the corner onto it — and it joins your party for the next level. The chapter runs through five maps: Oak's Lab, Viridian Forest, Viridian Pond, the Pewter City Entrance (where Team Rocket turn up) and Brock's Gym.

How to get through Pokémon Tower Defense

Fill the circles nearest the candies last: Place your strongest Pokémon on the first circles the wild Pokémon pass, so they take hits for longest. The circles by the candies are a last line, not the main one.
Level up between waves: Level Up costs the Pokémon's level squared in pokédollars — 25 at level 5, 100 at level 10 — and every defeat pays about 1.5 to 2.5 times the wild Pokémon's level. Early levels are cheap; spend on them as soon as the party box starts flashing.
Catch, do not only defeat: You start with a single Poké Ball and earn more by clearing a level for the first time. Use them on Pokémon that cover your starter's weakness; a second type in the party is worth more than a slightly faster win.
Read the starter card: Charmander is weak to Water, Ground and Rock, and the last level is a Rock-type gym. If you pick Charmander, catch something that hits Rock hard on the way.
Watch for status effects: Pokémon can be Asleep, Poisoned or Slowed. A slowed wild Pokémon stays in range longer, so moves that slow are worth keeping on a front circle.
Look twice at odd colours: Shiny Pokémon exist in this remake — the game announces "A shiny pokemon has appeared!" — and they can be caught like any other.

Key features

Five levels: Oak's Lab, Viridian Forest, Viridian Pond, Pewter City Entrance and Brock's Gym, each with its own cutscene.
Three starters: Squirtle, Bulbasaur or Charmander, with Pokédex cards that list type and weaknesses.
Catch and keep: Wear a wild Pokémon down to red health and throw the Poké Ball to add it to your party.
Real moves and types: Attacks, type matchups, sleep, poison and slow effects, experience and levels up to 100.
Saves in the browser: Your party, box, pokédollars and progress are kept in this browser between visits.
Mouse only: Everything is click and drag, so a Chromebook trackpad works as well as a mouse.

Pro tip: Charmander looks like the fun pick, but Brock's Gym at the end is Rock-type and Rock beats Fire. Squirtle and Bulbasaur both hit Rock hard — or pick Charmander and catch a Water or Grass Pokémon on the way.
