Canvas Tower Defense Unblocked

An endless neon tower defense with four turret types, three maps and ten upgrade levels per stat.

now playing: Canvas Tower Defense

Little red squares follow a glowing blue road, and every one that reaches the end costs you a life. You get money, open ground and four kinds of turrets. How long you last depends on where you build and what you upgrade first.

Canvas Tower Defense unblocked is based on Teddy Cross's open-source Canvas TD. There is no final wave, so each run is a contest against your own top scores, which the game keeps for each map in your browser.

How to play Canvas Tower Defense

Choose one of three maps: Loopy spirals toward the center, Backtrack folds back on itself, and Dash is one straight line. You start with $35 and ten lives. Waves of ten creeps arrive on a timer, and you can send the next one early whenever you feel ready.

Pick a turret and click open ground to place it. Turrets can't go on the road or overlap. Lasers, missiles, tazers and mortars each attack differently, and every turret can be upgraded in damage, fire rate and range. Upgrades get more expensive at each level, all the way up to $1,000.

A destroyed creep pays out money equal to the current wave number, so late waves are much more profitable. Creep health also climbs every wave. When ten creeps slip through and your lives hit zero, the run ends and your score is shown.

Tips

  • Start cheap. Lasers cost the least, so two early lasers give you coverage before the first wave lands.
  • Build where the road bends. A turret inside a curve can hit several stretches of path at once, especially on Loopy and Backtrack.
  • Slow them, then hit them. A tazer keeps the fastest creep in range of your heavy hitters for longer.
  • Upgrade a few turrets deeply. Creep health grows quickly, so one maxed-out turret often beats a field of weak ones.
  • Send waves early when you are comfortable. Extra waves bring extra kills and cash.

Canvas Tower Defense questions

How is the score calculated?

It is kills times total spending on turrets and upgrades. A sale refunds 70 percent, and that refund comes off your spending total, which drags the score down.

What happens when a turret maxes out all three upgrades?

At level 10 in damage, rate and range, it gains a bonus. Lasers may bounce a creep back to the beginning, missiles blast an area, tazers slow targets for good, and mortars set creeps on fire.

Can I speed up the slow early waves?

Yes. Turn on fast forward, or send the next wave yourself instead of waiting for the timer.

Does it work on a tablet?

Partly. You can tap to build and select turrets, but the screen is busy and the keyboard shortcuts help a lot, so a computer is the smoother choice.
