Follow the numbers. Dig the river. Riverdoku is a cozy logic puzzle game of water and stone. Every number on the board is how far the water has traveled from the spring. Work out where the river runs through the maze, and the stones are what is left. If you enjoy Sudoku, Minesweeper or Nonograms, here is a new number puzzle to fall for: every board has exactly one answer, and you reach it by logic alone. THREE SIMPLE RULES • Every square is either stone or water. • All water connects to the spring, and neighboring water differs by exactly one. • Water never flows in a circle. That's the whole game: a maze of numbers you untangle one square at a time. Tap to dig water, press and hold to lay a stone. A short tutorial plays your first river with you, move by move. Quick to learn, hard to put down. NO GUESSING, EVER Every logic puzzle is checked by a solver for a single solution, and for being finishable by deduction alone. There is always a next step you can work out, so these brain games reward careful thinking, never luck. 220 LEVELS IN SIX RIVERS Start on a relaxing 6×6 and work up to an 11×11 maze of stone. Solve every level of a river to earn its swimmer, who floats down your finished boards. A DAILY PUZZLE A fresh 7×7 brain game every day. Keep your streak, play the days you missed from the calendar, and set a daily reminder if you like. SEASONS AND SKINS TO EARN Solve every daily puzzle in a month to earn the next month's board and colors: twelve seasons, from Halloween and Christmas to Valentine's, Easter, Seaside and Moonshot. Two more boards are won on quests of twenty rivers: a quest through the shrubbery and a train chase across the carpet. PLAY WITH FRIENDS Open a room, share the six-letter code, and up to ten players race the same river at the same time. First to finish takes ten points. The host picks the difficulty, how many rivers to play and the time limit. QUICK PLAY A fresh logic puzzle whenever you want one, in Easy, Medium or Hard, with undo, three hints per board and your stats to beat. PLAY OFFLINE Everything except playing with friends works offline, so it's one of those offline puzzle games for the plane, the train or anywhere without wifi or a signal. CALM BY DESIGN A relaxing, cozy puzzle game: light and dark themes, calm sounds and haptics, each of which can be turned off. FREE TO PLAY Rivers 1 to 4 (140 levels), the daily puzzle, quick play, playing with friends, both quests and all twelve seasons are free, with one ad every ten boards. Riverdoku Premium is a single one-time purchase, not a subscription. It opens Rivers 5 and 6 (80 more levels), six more skins (a monster movie, a silent film, ink and mist, stained glass, a cat nap and a dog walk) and every river and skin added later, and removes the ads.
