Daily Tower Defense Challenge
Every day brings a new challenge. The Daily Tower Defense Challenge is generated from the date: the map, the towers you are allowed to use, your starting gold and lives, the number of waves and one special rule all change at midnight, your local time.
Everyone who plays on the same date gets the same challenge, so you can compare approaches with friends. Rules include a boss finale, only two tower types, a 5-life last stand, faster enemies, a tight budget, an armored tide and a target score. Some days are played on an open maze map.

- On maze days, walls and towers shape the enemy route; you cannot fully block it.

Towers
- Varies dailyTwo to five towers from the site's shared set: Bolt, Rapid, Sniper, Cannon, Frost, Poison, Lightning, Laser, Support and Ballista, plus Walls on maze days.
Every tower sells for 70% of everything spent on it. Upgrade costs are shown on the upgrade button.
Enemies
- Grunt, Runner, Brute, Guard, Swarmling, WardedThe standard enemy set, mixed according to the day's seed and rule.
- Daily Overlord (boss)Appears on Boss Finale days.
Strategy Tips
- Read the rule before placing anything. A Tight Budget day punishes early upgrades; a Last Stand day punishes any leak.
- On Two Towers days, work out which tower covers the other's weakness (for example Frost for fast enemies, Cannon for groups).
- On High Score Hunt days, kills and cleared waves give points, and every life left at the end is worth 100. Avoid leaks.
- Iron Tide days need armor-piercing damage. If there is no Ballista or Sniper, upgrade towers so they hit harder, because small hits fall off against armor.
About Daily Tower Defense Challenge
The Daily Challenge uses a seeded random number generator: today's date is turned into a number, and that number drives every choice. The same date always produces the same challenge, and no server is involved.
It reuses maps and towers from across the engine, which makes it a good way to try tower types you would not normally pick.
