Explore Our Rivers
Five games, five moods.
Some cards are tall and cinematic. Others stay compact and punchy. Why that rhythm? It keeps the catalogue feeling alive, especially on smaller screens where every swipe should reveal a little surprise.
Adventure
Pebble Quest
Part treasure hunt, part merge puzzle, with riverbank relics hiding in plain sight. Every level feels like a little expedition, and the reward path keeps opening up.
Simulation
Fish Tycoon
A compact management game about stocking tanks, balancing species, and keeping profit flowing. Simple on the surface, then unexpectedly tactical after a few upgrades.
Competitive
River King Tournament
Weekly challenges, live rankings, and catch streaks that keep the pressure on. Want a reason to return tomorrow? This one makes the answer easy.
Riverstone Merge – Dive Deep
A merge loop with real momentum.
Merge pebbles, driftwood, and shells to unlock more than 200 freshwater fish species, then build the aquarium you’ve been sketching in your head. Sounds calm, right? It is, until the progression chain starts snapping into place and every merge feels like a tiny win.
Core loop
Merge natural materials to reveal rarer species, decorate your tanks, and keep the collection moving forward with purposeful upgrades.
River exploration
Travel upriver through ten biomes, from marshland into glacier waters, with each stop bringing unique weather events, wildlife, and legendary catches.
Fishing mini-games
Cast, time the rhythm, and reel in rare fish that feed straight back into the merge progression. It keeps the loop feeling active instead of passive.
Community play
Weekly tournaments, fish trading, and seasonal Clean the River events give players a reason to show up together. Why play alone when the river can feel shared?
Stay in the loop
New fish, fresh events, and support that answers fast.
If you’re stuck on a level, chasing a tournament reward, or just want to ask what’s coming next, we’re here. Wouldn’t it be nicer to get a straight answer than to guess your way through a river?
