How to play
- Enemies walk down four lanes towards your base on the left. You can buy only the smallest tower, the Tier 1 tower.
- Place two Tier 1 towers side by side in a lane, then tap one of them to merge them into a Tier 2 tower. Merge two Tier 2 towers into Tier 3, and so on up to Tier 4.
- A tower that cannot merge is removed if you tap it, so only tap towers you mean to merge or remove.
- Survive six waves with your base standing to win.
Controls: mouse or touch. Made by CalcoTools.
Tips and strategy
- Two weak towers merged are far stronger than two weak towers apart.
- Keep pairs next to each other from the start, so a merge is one tap away.
- A Tier 3 tower is worth saving up for: it hits four times as hard as Tier 1.
- Do not merge in a lane that is about to be overrun: spend on more towers instead.
FAQ
- Can I buy bigger towers?
- No. Only the smallest tower is for sale. The bigger ones come from merging.
- Do the two towers have to be side by side?
- Yes, in the same lane and the next column along.
- What if I tap a tower with no partner?
- It is removed, without a refund.
