Rival Zoo: Logic & Wildlife

One animal per territory, row and column. Sounds simple, until the jaguar and the capybara can't stand side by side.

Rival Zoo is a logic puzzle game starring Brazil's wildlife. Each level is a board split into territories, and you must find the right spot for every animal by following rules inspired by nature. No guessing needed: every level has a single solution you can reach with reasoning alone.

RULES INSPIRED BY NATURE
• Rivals never touch, not even diagonally.
• Allies always stay together.
• Rivers are only for swimmers.
• Refuges protect whoever is inside them.
Each biome brings a new rule that changes how you think.

240 LEVELS ACROSS 6 BIOMES
Travel through the Pantanal, the Amazon, the Atlantic Forest, the Caatinga, the Cerrado and the Pampas. Every level you clear brings color back to a piece of the map of Brazil, and every win earns a piece of the biome's illustrated jigsaw puzzle.

HINTS THAT TEACH YOU TO THINK
Stuck? Hints don't just give away the answer: they show you the reasoning. You learn deduction techniques you can use in the levels ahead.
