Tidewall
Hold back the rising tide
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
The sea is rising and the raiders are coming. Build a wall of brick, iron, and grit — and hold the line.
Tidewall is a coastal defense game with the soul of a tower-defense classic. Stack walls, raise towers, post guards, launch boats and planes, and dig factories beneath the sand — then watch it all tested by the tide and everything that rides in on it.
DEFEND YOUR COAST
• Place walls, towers, and guards in a living side-view world
• Command naval units and aircraft; build underground factories for the long game
• Every wave hits harder — raiders dig, barricade, and chase
MANY WAYS TO PLAY
• Campaign — climb the levels and break through the boss fights
• Invasion & Aid Allies — push the offensive and survive the carrier boss
• Survival & Endless — one coast, no finish line, how long can you last?
• Chase — fast, taunting raiders that never let up
• Versus — duel the Commander offline, or send a link and battle a friend live
CLIMB THE GLOBAL BOARD
• Every run feeds your Career Score and earns badges
• Compare yourself against players worldwide on the leaderboard
PLAYS YOUR WAY
• One app, every language: English, Spanish, Brazilian Portuguese, German, and French
• Free to play. Optional Tide Pearls and a one-time "Unlock All Units" if you want a boost

Ratings & Reviews
Share your run: one tap opens the share sheet with your score and a link, so a friend can take the same coast. Optional reminders: say yes once and Tidewall will tell you when a new Daily Challenge is live or your coast is waiting — never during play, and off completely unless you ask for them. Also fixed: your stats no longer run together when a run ends, the readouts along the top no longer crowd the pause button on iPad, and translation polish across Spanish, Portuguese, German and French.
