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.

Hello! I really enjoy this game! Play it virtually every single day. However, I found some small bugs during game play that I wish to share, as well as some suggestions which I would really like to be added to the game if you wish. :) But a google review is not communication good enough, so expect an email from me when I get the minute! Otherwise, good work on getting a unique and enjoyable game out!

The game is overall a very nice and rewarding game.Its not too pay to win but you can pay to speed the progression which is reasonable. Now that the old royale and deep maps are here and sizu and leonhard are fixed,I haven't really ran into any bugs recently.I think the game is going in the right direction with the new online more.Now all you need to do is add more multiplayer modes such as team deathmatch and free for all.
