- Stop The Tsunami is a Roblox survival-building game where you dig walls to block giant waves.
- Digging is everything: each dig places wall segments automatically, so speed matters most.
- Claim daily rewards and join the official group for free pearls and bonus items like a rewind.
- Upgrade tools early: the lifeguard vehicle and mini excavator build walls far faster than the spade.
- Cover every edge: gaps in your wall let water through, so seal corners before starting a round.
Stop The Tsunami Basics: How the Game Works
In Stop The Tsunami, your single goal is to protect the city from increasingly massive waves. You do this by digging, which automatically places wall segments along the shoreline. Each round the waves get bigger, so your defenses must grow with them.

Your starter kit includes two digging tools with different behavior. Understanding the difference early saves you a lot of time on every round.
| Tool | What It Does | Best Use |
|---|---|---|
| Spade | Digs sand and creates wall segments | Basic round-one defense |
| Shovel | Digs an empty hole instead of a wall | Creating depth barriers and trenches |
| Special items | Rewind, time freeze, coin crates and more | Emergency saves during big waves |
Press the start round button only after your wall is finished. Waves arrive on your command, so there is no reason to rush while your defenses are incomplete.
Building Walls That Actually Hold
Wall quality decides whether your city survives. Beginners often build thin, uneven walls with open corners, and the water finds those gaps immediately. Build wide, seal every edge, and layer your defense.
The Wide Wall
- Dig multiple rows of wall segments
- Slows and absorbs big waves
- Reliable on every round
The Trench Line
- Use the shovel to dig deep holes
- Catches water before it reaches walls
- Works best with vehicle tools
The Great Wall
- Combine trenches plus stacked walls
- Handles late-game mega waves
- Needs the mini excavator or sand trencher
Key building habits that separate pros from beginners:
- Never leave corners open. Water pours through the smallest gap.
- Press G to build with placed materials like gold bars for extra reinforcement.
- Use the ocean pull-back warning as your timer. When the water recedes, stop digging and get ready.
- You can switch tools mid-round, so swap to repair weak spots between waves.
When you see the tsunami warning and the ocean pulling back, the wave is coming fast. Finish your current wall segment and step back rather than starting a new long trench.
Tool Upgrades and Shop Strategy
Pearls are your main currency, earned from daily rewards, round completions, and group membership perks. Spend them on better digging tools first, because faster digging directly translates into stronger walls within the round timer.
| Upgrade | Digging Speed | Best Feature | Rating |
|---|---|---|---|
| Spade (starter) | Slow | Free, always available | ★★ |
| Shovel (starter) | Slow | Digs deep holes | ★★ |
| Lifeguard ADV vehicle | Fast | Drivable digging vehicle | ★★★ |
| Bulldozer | Faster | Pushes and clears wide paths | ★★★★ |
| Mini Excavator | Very fast | Digs giant holes quickly | ★★★★★ |
| Sand Trencher | Fast | Creates long trench lines | ★★★★ |

Survive round one with the spade
Build a simple double-row wall and start the round. Small early waves are forgiving.
Save for the lifeguard vehicle
Your first vehicle purchase multiplies digging speed, making every later round easier.
Upgrade to the mini excavator
Giant holes plus fast digging let you build layered defenses against the biggest tsunamis.
Vehicles outperform hand tools at every stage. Prioritize the lifeguard vehicle, then the bulldozer, then the mini excavator before buying cosmetic items.
Round-by-Round Survival Checklist
Each wave is bigger than the last, and some rounds send multiple waves back to back. Treat your preparation as a repeatable routine instead of improvising every time.
Before Every Round:
- Claim daily reward and check for new codes
- Inspect last round's wall for broken segments
- Dig a full wall line with zero open corners
- Add a trench line in front using the shovel
- Confirm special items like rewind are equipped
- Stand clear of the shoreline before starting the round
Some rounds send several waves in sequence. Do not dismantle your wall after the first wave passes. Keep it standing, patch the damage, and let the layers absorb the follow-up.
FAQ
Q: What is the goal in Stop The Tsunami?
You must protect the city from tsunamis by digging, which automatically places wall segments. Each round brings bigger waves, so you need progressively stronger defenses and better tools.
Q: How do I get free pearls and rewards?
Claim the daily reward each day you log in, and join the official Roblox group for bonus items such as a free rewind. Round completions also pay out pearls you can spend in the shop.
Q: What is the difference between the spade and the shovel?
The spade digs sand and places wall segments, making it your main defense tool. The shovel digs an empty hole, which is useful for creating trenches that catch water in front of your wall.
Q: Which tool should I buy first?
Save for the lifeguard vehicle first. Drivable digging tools are dramatically faster than hand tools, letting you build wider, multi-layer walls before the tsunami warning expires.
Q: Why does water still get through my wall?
Almost always an open corner or a gap in the wall line. Water exploits the smallest opening, so walk the full length of your wall and seal every edge before starting the round.
