How do you play Tower Defense?
Jellies march along a fixed road. Build towers on the empty tiles beside it, pop the jellies, and keep at least one of your 20 lives through wave 30 to win. Each jelly that reaches the cake costs one life, and a King jelly takes five.
Popping jellies earns in game coins that you spend on new towers and upgrades. There is no real money and nothing to buy. Pick from five maps and three difficulty levels: Easy, Normal and Hard.
What towers can you build?
| Tower | Cost | What it does | Best against |
|---|---|---|---|
| Squirt | 50 | Fires quick, light water shots at one jelly. Range 2.5 tiles | Regular, speedy and winged jellies |
| Candy Cannon | 85 | Lobs a cotton candy ball that splashes every jelly near where it lands | Tight groups |
| Frost | 70 | Slows every jelly in range and deals a little damage | Speedy jellies and the King |
| Zapper | 120 | Lightning that jumps from jelly to jelly, hitting 3 to 5 of them | Long lines and tough jellies |
Each tower can be upgraded twice, up to level 3, gaining damage and range each time. Selling returns 70% of everything you spent on it. Tap a tower to see its range as a dotted circle.
What kinds of jellies are there?
- Jelly: the common green one.
- Speedy jelly: low health but almost twice as fast.
- Tough jelly: slow and beefy, and it shrugs off 3 damage from every hit, so weak shots barely scratch it.
- Winged jelly: flies along the same road and only takes half the slow from Frost towers.
- King jelly: a crowned giant in waves 10, 20 and 30 with huge health. Letting it through costs 5 lives.
Why call the next wave early?
Once a wave has fully spawned, the next one starts 14 seconds later. Calling it early with the Next button pays bonus coins for every second you skip. The waves will overlap, so only do it when your defense has room to spare.
Tips
- Build on the inside of corners. The more road inside a tower's range circle, the longer it keeps firing.
- Put a Frost tower in front of your damage. Slowed jellies stay in range of everything else for longer.
- Tough jellies need big hits. Mix in Candy Cannons and Zappers instead of only adding Squirts.
- Upgrade before wave 10. The first King jelly has a lot of health and level 1 towers struggle.
- Fast forward only when things are calm. If it gets tight, pause and plan your next tower.
