Quick Guide
  • Stop The Tsunami badges are earned by surviving waves, building strong defenses, and hitting survival milestones.
  • Survival rounds are the core path: each tsunami you stop pushes you toward badge thresholds.
  • Upgrade tools early: better shovels, sand trenchers, and glue dramatically boost your odds.
  • Dig a backup trench behind your wall to catch overflow water during double waves.
  • Claim daily rewards and spins before every session for free skins and pearls.

Badges Overview: What They Are and Why They Matter

In Stop The Tsunami, badges act as permanent milestones tied to your performance across survival rounds. Every time you and your wall hold back a tsunami, the game records the result, and badges reward consistency — surviving multiple waves in one run, lasting through late-game mega tsunamis, and stacking up coins through successful defenses. Players who chase badges are essentially chasing mastery of the game's core loop: dig sand, build the wall tall, reinforce it, survive, repeat.

The key insight for badge hunting: badge progress scales with how long you last and how many waves you stop. A single tall, glued, tamped wall that survives five waves is worth far more than rebuilding a flimsy wall ten times.

Core Badge Principle

Focus on wall quality over wall speed. A compact, tamped, and glued wall that survives repeated waves generates badge progress faster than a sprawling untamped wall that collapses on round two.

Badge Types and Unlock Conditions

Badges in Stop The Tsunami generally fall into survival-based categories. While exact thresholds can shift between updates, the table below covers the badge families and what typically triggers them.

Badge CategoryTrigger ConditionDifficultyRecommended Prep
First SurvivalStop your first tsunami★☆☆☆☆Any basic wall on Easy solo
Wave StreaksSurvive consecutive waves in one run★★☆☆☆Tall wall + glue + tamper
Mega TsunamiSurvive the "ocean pulls back" event★★★★☆Max-height wall + rear trench
Coin MilestonesEarn set amounts of coins from survivals★★☆☆☆Speed upgrades + 2x speed rounds
Tool MasteryPurchase and use key tools (trencher, tamper, glue)★★★☆☆Farm coins on early easy rounds
Watch for the Mega Wave

When the game warns "The ocean is pulling back, something huge is coming," a massively larger tsunami is inbound. This is the moment most badge runs fail — start digging and stacking sand immediately, and do not start the next round until both sides of your wall are built up.

Step-by-Step Badge Run

1

Claim Freebies First

Before your first round, use your daily spin for skins and claim pearls from the rewards menu. Pearls fund early upgrades, and skins are free cosmetics — never skip this step.

2

Build the Starter Wall

Dig sand near the shoreline and toss scoops onto the wall line. The taller the wall, the better it stops the first waves. Click Start Round only when the wall looks evenly high across its length.

3

Reinvest in Tools

At around 300 coins, buy the sand trencher — it digs far faster than the starter shovel. Follow up with the tamper, glue bottle, and shovel upgrades as coins allow.

4

Reinforce Every Cycle

After each survived wave, dig behind the wall and move fresh sand onto it. Tamp it down for sturdiness and glue the back face — glued sand does not slide, making the wall far more impact-resistant.

5

Survive the Mega Tsunami

When the pull-back warning fires, use 2x speed to stack sand rapidly, dig a rear trench to catch overflow, and keep both flanks built high. Surviving this event is the gate for the hardest badges.

Trench Trick

Digging a deep trench directly behind your wall catches any water that crests the top. Even when a wave splashes over slightly, the trench absorbs it — this single technique turns borderline failures into survivals.

Best Tools for Badge Hunting

Sand Trencher (300 coins)

  • Fastest digging tool
  • Moves sand onto the wall automatically
  • Slower to turn, plan your passes

Tamper

  • Knocks wall down slightly
  • Compacts sand into a sturdy, impact-proof wall
  • Worth the height trade-off

Glue Bottle

  • Glued sand will not slide
  • Fastest reinforcement option
  • Apply to the wall's back face first

Additional purchases worth considering:

ToolCost TierBadge ValueNotes
Shovel UpgradesLow★★★☆☆Faster scoops, immediately useful
TamperMid★★★★☆Best durability per coin
Glue BottleMid★★★★★Fastest reinforcement in the game
Sculpting TrowelMid★★☆☆☆Smooths uneven wall sections
Lifeguard ATVHigh★☆☆☆☆Finicky; pushes sand but hard to control
Stompy WallsHigh★★★☆☆Harder, longer-lasting walls
Upgrade Priority

Buy in this order: shovel upgrade → sand trencher → glue → tamper. The lifeguard ATV is fun but unreliable for serious badge runs — manual digging with upgraded tools outperforms it.

Badge Run Checklist

Before Every Badge Session:

  • Claim the daily spin and free pearl rewards
  • Confirm shovel and trencher are upgraded
  • Build wall evenly before starting the round
  • Glue and tamp the wall between waves
  • Dig a rear trench before the mega tsunami warning

FAQ

Q: How do I earn Stop The Tsunami badges fastest?

Survive consecutive waves in a single run on Easy solo. Each survived tsunami counts toward badge progress, and a tall, glued, tamped wall that lasts several waves earns far more than repeated short runs.

Q: What is the mega tsunami and how do I survive it?

When the game says the ocean is pulling back, a much larger wave is coming. Build the wall as high as possible on both flanks, dig a trench behind the wall to catch overflow, and use 2x speed to stack sand before impact.

Q: Which tool should I buy first?

Save around 300 coins for the sand trencher first — it dramatically speeds up digging. Then prioritize the glue bottle and tamper, since glued and compacted walls survive far more waves than loose sand.

Q: Does the lifeguard ATV help with badges?

It can push sand into the wall, but it is finicky and slow to control. Upgraded shovels and the trencher generally outperform it, so treat the ATV as a fun extra rather than a badge-hunting tool.
