About this game

Fish Royale is a fish eat fish io game with a huge single-player adventure and real online multiplayer. Eat smaller fish, grow into a shark and climb the food chain through a full campaign of stages and boss fights, then take your fish online for real-time battles, 1v1 duels and co-op with a friend. Over 30 playable fish are waiting.

EAT. GROW. DOMINATE.
You start as a tiny fish in a big ocean. Eat anything smaller than you, dodge anything bigger, and keep growing until the predators that chased you are the ones swimming away. Eat and grow, or get eaten. Simple to pick up, brutal to master.

🗺️ A HUGE SINGLE-PLAYER ADVENTURE
Fight your way through a full campaign packed with stages, challenges and boss fights. Every level is a new underwater food chain to climb, and Kessler is waiting at the top of one of them.

🦈 OVER 30 PLAYABLE FISH, INCLUDING SHARKS
Unlock more than 30 characters, from small fry to several species of shark and other apex predators, and find the one that matches how you hunt. Fast and sneaky, slow and armored, or big enough to eat the whole map.

⚔️ ARENA — FREE ONLINE MULTIPLAYER
Real-time multiplayer battles against real players. Drop into a live arena, eat your rivals, grow bigger than everyone and finish as the biggest fish in the lobby. Arena is free for everyone.

🆚 VERSUS — 1v1 WITH A FRIEND
Challenge a friend to a best-of-3 1v1 duel. Every round ends on a slow-motion replay of the deciding bite, so there's never an argument about who got eaten.

🤝 CO-OP — PLAY THE CAMPAIGN TOGETHER
Team up with a friend and play the whole adventure in co-op, boss fights included. Kessler is a different beast when there are two of you in the water.

A game like those old apps from 2010 where games actually had levels, progress you could see and feel, and REAL accomplishments, not just endless clicking machines that satisfy small gratification hunger in our brains. There is an energy bar but a fairly reasonable upgrade cost for the unlocked game is a fair ask for a game that doesn't shove ads in your face. Good to have games that really feel like the old days again. Comfortable controls! Small text is slightly hard to see.

This is definitely one of my all time favorite games of all time. It's fun to play, I love the different fish and abilities that make a unique play experience with each one. The boss levels were great and the over all level design is amazing and really makes you feel like your swimming the ocean. Each update never fails to disappoints and gives new fish to unlock. Maybe a stingray & otter for next update? Glitch with gem challenge not progressing was fixed :)
