What Are Pearls in Stop The Tsunami?
Pearls are one of the main currencies in Stop The Tsunami, a Roblox defense game where you dig sand, stack walls, and hold back escalating tsunami waves. When you first join a server, two free sources are immediately available: the Daily Spin, which grants skins you can equip in the Skins menu, and the Rewards menu, where you can claim Pearls directly.
Pearls are primarily used to purchase upgrades, which meaningfully improve your digging power and defensive options. Because early rounds are easy, smart players claim every free pearl source before clicking Start Round.

Always grab your Daily Spin and Rewards Pearls the moment you join. Upgrades bought with early Pearls compound over every round you survive.
How to Earn Pearls & Coins Fast
There are two income streams in Stop The Tsunami, and they work on different loops. Pearls come from the Rewards menu and special claims, while Coins drop from surviving tsunami rounds. The more waves you stop, the more coins you accumulate for tools and gear.
| Currency | Main Source | Best Use | Earn Rate |
|---|---|---|---|
| Pearls | Rewards menu, Daily Spin claims | Permanent upgrades, skins | Fixed claims per day |
| Coins | Surviving tsunami rounds | Tools, machines, shovels | Scales with wave count |
| Skins | Daily Spin | Cosmetics in Skins menu | One free spin daily |
Every round you survive is a coin payout. A tall, glued, tamped wall that survives back-to-back waves (including surprise double waves) is the most reliable farming method in the game.
Ways to maximize income per session:
- Play solo on Easy for low-risk coin stacking while learning mechanics
- Keep rounds running at 2x speed once your wall is proven
- Rebuild between waves instead of idling — dig constantly
- Watch for the "The ocean is pulling back" warning; it signals a massive wave worth preparing extra height for
Step-by-Step: First Round to First Upgrades
Claim Freebies
Join the game, use the Daily Spin for skins, and claim Pearls from the Rewards menu before doing anything else.
Dig and Stack
Dig up sand near your build zone, then throw scoops onto your wall line. Height is the single most important stat — the taller, the better.
Start the Round
Click Start Round and let the tsunami hit. A sufficiently tall wall stops the first waves outright, saving the town and paying out coins.
Reinvest Coins
At around 300 coins, buy the Sand Trencher to dig faster, then upgrade your shovel for bigger scoops per trip.
Harden the Wall
Use the Tamper to compact sand and the Glue Bottle to lock sections in place. Glued sand slows erosion, and tamped walls resist impact.
Some rounds spawn two waves back to back. Never assume a survived wave means the round is over — keep digging the moment the water recedes.
Best Tools & Upgrades Compared
Coins and Pearls both funnel into equipment. Here is how the main purchases stack up against each other:
| Tool / Upgrade | Cost Range | Effect | Rating |
|---|---|---|---|
| Shovel Upgrades | Moderate coins | Bigger scoops, faster digging | ★★★★★ |
| Sand Trencher | ~300 coins | Auto-digs and pushes sand toward the wall | ★★★★ |
| Tamper | Coins (machines) | Compacts wall so it resists breaking on impact | ★★★★ |
| Glue Bottle | Coins (war tools) | Glued sand erodes far slower in water | ★★★★ |
| Sculpting Trowel | Coins | Smooths and shapes wall sections | ★★★ |
| Lifeguard ATV | Higher coins | Pushes sand into the wall; finicky controls | ★★ |
Speed Build
- Sand Trencher + big shovel
- Fastest sand throughput
- Best for repeated solo farming
Durability Build
- Tamper + Glue Bottle
- Walls survive impact and erosion
- Best for late massive waves
Hybrid Build
- Trencher into tamped, glued wall
- Dig a rear trench to catch overflow
- Strongest all-round setup
Dig a trench directly behind your main wall. Any water that crests the wall collects in the trench instead of flooding the town — a cheap second line of defense.
Session Checklist & Wall Standards
Use this checklist each session to make sure you are claiming every Pearls source and building to a survivable standard before starting rounds.
Every Session Checklist:
- Claim Daily Spin and Rewards Pearls on join
- Buy or verify your upgraded shovel before round 1
- Stack the wall taller than the previous wave crest
- Tamp and glue the wall's front and back faces
- Dig a rear overflow trench before big-wave warnings
Wall quality benchmarks by wave difficulty:
| Wave Threat | Wall Height | Reinforcement | Trench Needed |
|---|---|---|---|
| Early waves | Medium | None required | Optional |
| Mid waves (double waves) | Tall | Tamper recommended | Yes |
| "Ocean pulling back" mega wave | Maximum | Tamper + Glue | Strongly advised |
The mega wave — announced when the ocean pulls back — will crest low walls with ease. If you hear the warning and your wall is short, drop everything and dig.
FAQ
Q: How do I get Pearls in Stop The Tsunami?
Pearls are claimed from the Rewards menu when you join the game. Log in daily and claim them before starting rounds, then spend them on upgrades that improve digging speed and wall durability.
Q: What should I spend Pearls on first?
Prioritize upgrades that increase digging efficiency. Faster digging means taller walls, and taller walls mean more survived rounds — which compounds into more coins for tools like the Sand Trencher and Glue Bottle.
Q: Why did my wall fail even though it looked tall?
Two common reasons: a surprise second wave in the same round, or unreinforced sand eroding on impact. Use the Tamper to compact the wall and the Glue Bottle so water strips material more slowly, and dig a rear trench to catch overflow.
Q: Is the Lifeguard ATV worth buying?
It can push sand into the wall to grow it, but the controls are finicky and it is slower than simply digging with an upgraded shovel. Treat it as a late-game novelty rather than a core farming tool.
