How to Play Underwater Arcade Games
Start here. What every game on this site shares: how to start, what the HUD means, and the three control schemes you will meet.
Underwater Game Guides
Written walkthroughs and technique notes for the games on this site. Each guide is built from actual play, not from a specification sheet — the numbers quoted are the numbers in the code.
These guides are organised by what you are trying to do rather than by game. If you want to stop crashing in a canyon, the submarine guide covers it regardless of which submarine game you are playing. If you keep drowning with a full load of treasure, the air-management guide is the one.
All eight guides are free, none require an account, and each one links directly to the games it describes so you can try a technique the moment you read it.

Frequently asked questions
Are these guides written by someone who has played the games?
Yes. Every guide on this site is written after playing the game it covers, and the numbers quoted — spawn rates, multiplier caps, oxygen costs, gap widths — are read from the game code rather than estimated. That is only possible because all eight games were written for this site.
Do the guides cover games on other websites?
No. These guides cover the eight games published here. Advice about momentum control, route planning and combo protection transfers well to similar games elsewhere, but the specific numbers will not.
How often are the guides updated?
A guide is updated when the game it describes changes, when a reader reports something that no longer matches, or when a technique turns out to be wrong. The 'last updated' date only moves when the text actually changes — see the editorial policy.
Which guide should I read first?
If underwater arcade games are new to you, read 'How to Play Underwater Arcade Games' for the shared basics and then the beginner's guide for a suggested playing order. If you already play and want better scores, go straight to the high score guide.
Are the guides suitable for mobile players?
Yes, and one guide is specifically about playing on a phone. Every other guide notes where touch controls behave differently from a keyboard, because in several games they genuinely do.
Prefer the wider picture?
Guides are practical documents about playing better. If you would rather read about the genre itself — how it is built, which games are worth trying and where the design ideas come from — the articles section covers that ground, starting with the ultimate guide to underwater arcade games.
