Obby: Fish training

Obby: Fish training - Play Online

This is a Roblox-style underwater simulator where you collect pets, ride mounts, and grind your way through checkpoint arches to unlock bigger fish forms. If you've ever played Pet Simulator X, you'll recognize the formula immediately—blocky pets follow you around while you race through zones collecting energy orbs. The goal is simple: swim fast, hatch pets from boxes, and rebirth to reach new ocean depths. It's pure casual progression with leaderboards thrown in for bragging rights.

Key Features

• Pet Collection System: Hatch cube-shaped underwater creatures from gacha boxes to boost your stats.
• Mount Variety: Ride dolphins, turtles, and unlock more powerful sea creatures as you progress.
• Rebirth Mechanic: Reset your progress to unlock new underwater eras and permanent speed boosts.
• Tournament Leaderboards: Compete to become the fastest swimmer and show off your rare pets.

How to Play Obby: Fish training

The loop is simple to grasp but designed to keep you grinding for hours.

Start Swimming and Collecting Energy

You control your fish using WASD on desktop or the virtual joystick on mobile. Your job is to swim through the underwater zones, passing through rainbow checkpoint arches and grabbing floating orange canisters. These give you currency to unlock the next area. Jump with Spacebar when you need to clear obstacles or reach higher platforms. The camera rotates with right-click, and you zoom with the scroll wheel.

Hatch Pets and Equip Mounts

Once you've collected enough energy, head to the pet hatching stations. You'll get random blocky pets that follow you around—the rarer ones give bigger stat boosts like speed or currency multipliers. You can also unlock mounts like dolphins and turtles that let you move faster through the map. The VIP portal offers premium options if you're willing to pay, but you can grind everything for free if you're patient.

Rebirth to Unlock New Depths

When you hit a wall in progression, the rebirth system resets your fish form but gives you permanent bonuses. This unlocks deeper ocean zones with tougher challenges and better rewards. The cycle repeats—collect, hatch, rebirth—until you're at the top of the leaderboard or you've run out of things to unlock.

Who is Obby: Fish training for?

This is a kids' game through and through. If you're between 6 and 12 and love Roblox simulators, you'll feel right at home. It's designed for low-friction fun—no real skill required, just time investment. Perfect for casual players who want to zone out and watch numbers go up. If you're looking for deep mechanics or challenging gameplay, this isn't it. It's all about the dopamine hit of hatching a shiny new pet.

The Gameplay Vibe

It's super chill and repetitive. You're basically running the same loop over and over: swim to checkpoint, collect orbs, hatch pet, repeat. The visuals are basic Roblox quality—flat shading, low-poly models, and tiling textures with visible seams. The water effect is just a scrolling transparent plane. There's minimal audio feedback, so you'll probably want to throw on a podcast or music while you play. It's not stressful at all, just a mindless grind that feels weirdly satisfying if you're into progression bars.

Technical Check: Saves & Performance

The game saves your progress automatically in your browser cache, so you can pick up where you left off. Just don't clear your browsing data or you'll lose everything. Performance-wise, this runs on a potato—the graphics are intentionally low-end to work on cheap phones and old PCs. I didn't experience any lag or stuttering, even with multiple pets following me around. It's optimized for accessibility, not beauty.

Quick Verdict: Pros & Cons

A solid time-waster if you're into Roblox-style simulators, but don't expect originality.

• ✅ Pro: Zero learning curve—jump in and start grinding immediately.
• ✅ Pro: The rebirth system keeps you hooked for "just one more unlock."
• ❌ Con: Extremely repetitive gameplay with low originality—feels like a reskin of a hundred other pet simulators.

Controls

Responsive enough for what the game demands—no precision platforming here, just basic movement.

• Desktop: WASD to move, Spacebar to jump, Right Mouse Button to rotate camera, Scroll Wheel to zoom.
• Mobile: Virtual joystick for movement, on-screen button for jumping, swipe and pinch for camera control.
