In Tower Defense you place towers along a path to stop incoming waves from reaching the end. Free, no install, no account.

In Tower Defense, enemies walk a fixed route down to the exit. Points from each cleared wave are what you spend on new towers.

Place towers
Put towers on open ground beside the path to cover it.
Earn and build
Each wave cleared gives you points, and points are what you spend on new towers.
Cover the route
Make sure every stretch of path is within a tower's reach.
Survive the waves
Hold out through all waves; if too many leak through you lose.

Cover the corners, not the length
The path doubles back on itself, so the same stretch of ground can sit within range of a tower covering a different stretch. Placing towers at the bends is worth more than spreading them evenly along the road, because that is where enemies spend the most time in range. Before you build, look for the spots that cover two bends at once.
Your opening money buys three towers
You start with 60 and a tower costs 20, with the same 3 damage per shot for every tower and no upgrades available. So the first decision is not which tower is strongest, it is where three towers do the most work together. The waves grow from 6 to 9 to 13 enemies, each with more health and a faster walk, which is why placing early beats waiting to see what is coming.
Kills pay for the next tower
Each enemy you destroy hands back money, and the amount grows with each wave, so a tower that holds the early waves is what funds the ones you need later. Towers cannot be upgraded or moved once placed, so money you do not spend is money wasted. You also only lose a life when something reaches the end, which makes each tower a decision about where a leak would hurt most.
