Stop The Tsunami Wiki

Stop The Tsunami! is a Roblox dig-and-defend experience by creator jzf25. A giant wave is coming for the town. Your job is simple to say and demanding to master: dig sand, pile it into walls, carve trenches, pack everything hard, press START ROUND, and earn coins when the shoreline still stands. Clear a stage and the sea pulls back — the beach gets wider, the waves get bigger, and the same soft sand habits that worked on Easy stop working on Hard.

This wiki is the English overview hub for progression systems, co-op habits, and the pages players search most. The live place sits in the multi-million visit band (~5.6M+ visits, ~100k+ favorites as of mid-November 2026) with busy concurrent windows often in the tens of thousands. Play the experience on Roblox, then use the links below when you need upgrade order, material ranks, controls, daily freebies, or code checks. There are no active promo codes yet (November 2026); the Codes page tracks that status so you do not chase expired lists.

How a round works

Every successful loop has the same spine. Dig to create volume. Shape walls and trenches so flanks are not open. Pack loose piles — unpacked sand fails even when it looks tall. Start the round only when the line is ready. Survive for coins. Spend those coins on better tools and heavier fill. Repeat as the beach widens.

Early gear starts at a toy spade. Climb through shovels, a bulldozer, a skid steer, excavators, and a dump truck. Late beach work adds gravel, boulders, clay, and concrete for walls that can take a monster wave. Machines win the prep clock; materials win the impact. Rank both in the Tier List section instead of guessing from the shop UI.

Difficulty modes are Easy, Medium, and Hard. Easy teaches packing. Medium punishes soft edges. Hard expects late machines and high-tier fill on a full beach. Daily Spin and daily rewards feed the economy — see the Daily Rewards Guide. Join the Beach Club group for a free Rewind when a learning run goes wrong — steps and Rewind timing live on the Beach Club Rewind Guide.

Co-op is the default design

Multiplayer shares one coin wallet and every machine. One player digs, one drives, one patches the wall mid-wave. Impulse buys tax the whole lobby. Good etiquette — calling START ROUND, parking vehicles for the next driver, packing before flexing concrete — matters as much as raw dig speed. Read Players for roles and Guides for full walkthroughs including getting started, upgrades, defenses, and co-op detail.

Solo players still win by alternating digger and packer roles in one body. Never treat START ROUND as a panic button while piles remain fluffy.

What each hub is for

• Codes — active and expired promo codes, redemption in the lobby CODES area, and “no active codes yet” status when the list is empty.
• Scripts — script-related notes for players who search that keyword; use caution and common sense with any third-party executor content.
• Tier List — machine ranks (excavator and dump truck on top) and material ranks (concrete down through packed sand).
• Guides — how-to pages for first hour play, Daily Rewards, Beach Club Rewind, upgrades, defense building, co-op, and Hard mode.
• Players — roles, etiquette, difficulty choice, and the Controls breakdown for PC and mobile.
• Updates — patch and content change notes, including the current November 2026 Status snapshot.

Internal links on this wiki use trailing slashes and stay locale-agnostic in source form so every language build resolves correctly. Prefer anchored text like Build Defenses over bare URLs.

Progression priorities at a glance

1. Survive Easy with packed sand walls and clean trenches.
2. Buy shovels, then mid machines when dig speed stalls.
3. Add gravel and boulders as Medium leaks appear.
4. Unlock excavator and dump truck for late clear and haul.
5. Climb clay and concrete for Hard on the widened beach.
6. Recheck Codes after updates; redeem only in the official lobby flow.

Images on the site — beach clear shots, wave impact stills, and home hero art — match the live Roblox experience so you can orient landmarks while reading. Favicon and theme accents follow the coastal cyan look of the game branding.

How to use this wiki well

Start on this overview, open Guides for step-by-step play, then pin Tier List when you have coins to spend. Claim lobby freebies with Daily Rewards and Beach Club Rewind before long grind blocks. After a failed Hard attempt, compare your wall face to the materials ranking and your prep time to the machine ranking before blaming RNG. When friends join, send them Players so roles are clear before the first START ROUND. After a Roblox update stamp (such as the 14 November 2026 window), skim November 2026 Status and the Updates Hub checklist.

This is a fan-made Roblox wiki for Stop The Tsunami! — not an official jzf25 publication. Facts such as shared wallets, Beach Club Rewind, machine order, and material ladder are kept aligned across pages; if a patch changes unlocks, update notes will land under Updates and the related guides will follow.
