Getting Started in Stop The Tsunami

This is the day-one walkthrough for Stop The Tsunami! on Roblox. A tsunami is coming for the town. You dig sand on the beach, pile it into walls, carve trenches, pack everything hard, then press START ROUND and watch the wave. Survive and you earn coins. Spend those coins on better tools and machines so the next, wider beach does not wash you out. Creator jzf25 built the experience; this guide gets you from join screen to a held Easy wave without wasting your first payout.

If you need button mappings while you dig, keep the controls page open in another tab. When you are ready to specialize, jump to Build Defenses and Upgrade Machines.

Step 1 — Join and settle in the lobby

Launch Stop The Tsunami! from Roblox. Land in the lobby, look around for the CODES redemption area, the Daily Spin, and daily rewards. Even if you are itching to dig, clear lobby chores first so free value is not left on the table.

Claim Daily Spin and daily rewards

Every session, spin the Daily Spin and collect daily rewards before you enter a serious run. Early coins and materials compound: a free shovel step or a small coin bundle can be the difference between a packed wall and a toy-spade ridge that folds on impact. Make this a habit the same way you would check inventory in any progression Roblox game. For lobby claim order, streak habits, and co-op etiquette around freebies, open the Daily Rewards Guide.

Redeem codes if any exist

Walk to the lobby CODES area and try any strings listed on our Codes Hub. As of November 2026 there are no active public codes, but the UI works — redeeming takes seconds and costs nothing. Recheck the Codes Hub whenever the game updates.

Join Beach Club for free Rewind

Join the Beach Club group associated with the experience. Membership grants a free Rewind. Rewind is your safety net when you press START ROUND too early, leave a gap in the wall, or learn Hard mode the painful way. Claiming it on day one means your first experimental walls are less punishing. Full join steps and good vs bad Rewind calls live on the Beach Club Rewind Guide.

Step 2 — Learn the beach loop on Easy

Select Easy for your first sessions. Easy waves forgive crooked walls and teach the core loop without demanding gravel or excavators.

Dig sand

Equip the toy spade and dig where the shoreline needs mass. Scoop consistently instead of peppering random holes. You are mining the raw material that becomes your wall — every scoop should feed a planned pile, not decorate the beach.

Pile into walls

Drop sand into a continuous barrier across the approach the tsunami will take. Aim for even height and no visible gaps. A short tall spike with open flanks loses; a lower continuous ridge that you can pack usually wins on Easy. Think fence, not sculpture.

Carve trenches

Trenches shape flow and give you working space. Dig a clean trench line that supports the wall face instead of undercutting the foundation. Sloppy trenches create collapse points the wave will find instantly.

Pack hard

Loose sand looks like a wall until water hits it. Pack the structure until it feels dense and unified. Unpacked piles shear; packed walls hold long enough to earn coins. If you only remember one Easy tip, remember pack before START ROUND.

Step 3 — When to press START ROUND

Press START ROUND only when:

1. The wall spans the critical line with no gaps.
2. Height is roughly even end to end.
3. Trenches are finished and not cutting under the base.
4. The structure is packed hard.
5. You (and friends, if any) are off the dig tools and ready to watch or patch.

Starting early to “see what happens” burns build time and Rewind charges. Watch the wave, note where water climbs or breaches, then rebuild smarter. Surviving pays coins; dying teaches, but coins teach faster when you survive on purpose.

Step 4 — Earn coins and buy the first shovel

Held waves drop coins. Your first meaningful upgrade is leaving the toy spade for a real shovel. Dig speed is the bottleneck on Easy: faster dig means taller packed walls before the lobby timer in your head says go. Do not save endlessly for a dump truck while you still scoop with a toy — mid-game machines shine after the beach widens, which happens once you clear stages with reliable Easy clears.

Use the machine tier list after that first shovel to plan bulldozer, skid steer, excavators, and dump truck. The full shopping order and beach-widening breakpoints live in Upgrade Machines.

Step 5 — First-hour checklist

1. Join the game and open the lobby.
2. Claim Daily Spin + daily rewards.
3. Check Codes and redeem anything live.
4. Join Beach Club → free Rewind.
5. Skim controls.
6. Enter Easy, dig, pile, trench, pack.
7. Press START ROUND only when packed and continuous.
8. Bank coins → buy first shovel.
9. Repeat until walls feel boring — then read Build Defenses.
10. When friends join, switch to the Co-op Guide role split.

Common day-one mistakes

Starting the round on a hollow pile. If you can still see loose texture or soft edges, pack more.

Building a monument in the middle and ignoring flanks. Water finds edges. Seal the line.

Ignoring daily rewards. Free progression is free progression.

Skipping Beach Club. A free Rewind is the cheapest insurance in the game.

Hoarding coins past the shovel upgrade. Throughput beats vanity on day one.

Jumping to Hard immediately. Learn Easy packing first; Hard expects stronger materials and team roles covered in Hard Mode.
