Clockwork Causeway
Clockwork Causeway is a tower defense game that plays in the browser on phones, tablets and computers, for one player.
Build wind-up towers on brass plates beside a causeway to stop clockwork pests over 12 waves. Every tower runs down during a wave and fires slower as it does, so you tap towers to rewind them. Winning a map opens the next of eight, and stars for few leaks buy permanent perks.
How to play
- Tap a brass plate and build a tower
- Send the first wave with Next wave
- Towers run down: tap one to rewind it
The game shows these steps as you play, the first time.
Controls
- Tap a plate to build
- Tap a tower to rewind it (or, when full, upgrade or sell)
- Space sends the next wave
- Esc pauses
Tips
- Springs unwind only while a wave runs, and an empty one fires at a quarter speed, so rewind every low tower in the pause before sending the next wave.
- Kettles carry three armour that comes off every gun and mortar hit, but the Coil Zapper ignores armour and chains to three pests, so build one before wave four.
- Sending the next wave early while pests are still on the road pays 15 coins, and each cleared wave pays 25, so a strong defence can afford to hurry.
Why can the mortar not hit some pests?
The Spring Mortar lobs shells at the ground, so Kites, which fly, pass over it untouched; they appear from wave five on the second map onward. It also cannot fire at anything right next to itself. Gear Guns, Coil Zappers and Fans all reach fliers.
How are stars and perks earned?
Holding a map with no leaks gives three stars, three leaks or fewer gives two, and any win gives one; the best result per map is kept. Stars buy five permanent perks: 40 extra start coins, five extra lives, a quarter-second rewind, 15% sharper Gear Guns and springs that last 30% longer.
