Duorva: Logic Puzzle Game

Balance Fire and Water, Earth and Wind! 50 handcrafted levels, a new Daily Puzzle every day and endless 4×4 to 8×8 puzzles. Play offline.

Duorva is a logic puzzle where you balance Fire and Water, Earth and Wind. The rules take seconds to learn, yet every level asks you to think one step further. If you enjoy sudoku, takuzu and other brain teasers, Duorva is made for you.

HOW TO PLAY

• Every row and column holds an equal number of both elements. • No more than two of the same element can sit next to each other, horizontally or vertically. • Cells joined by = must match; cells joined by × must differ. • Tap a cell: Empty → first element → second element → Empty.

Every puzzle has exactly one solution and can be solved by logic alone, with no guessing.

WHAT'S INSIDE

• Two worlds: Fire & Water and Earth & Wind. Earth & Wind adds new rules such as the Earth Layer and the Wind Vortex. • Campaign: 25 handcrafted levels in each world, carefully ordered from easy to hard. • Daily Puzzle: a new puzzle every day; keep your daily streak going. • Unlimited: Easy, Normal and Hard puzzles on 4×4, 6×6 and 8×8 boards that never run out. • Smart hints: a hint does not just give the answer, it shows step by step why a cell must be Fire or Water. • Balance Crystals: earn crystals by finishing levels and the Daily Puzzle, then spend them on hints. • Interactive tutorial: learn the rules by playing. • Undo, redo, erase and pause; your progress is saved automatically. • Play offline, no internet connection needed. • Available in English and Turkish.
