Yadoku

01Factsheet

02Description

Yadoku is a daily dice-placement puzzle. You roll sixteen dice one at a time and place each one onto a 4x4 grid. Every row and column is then scored for a combination: Two Pair, Small Straight, All Odds, All Even, or Four of a Kind. A single die counts toward both its row and its column, so every placement is a small optimization problem. Think of it as a mini-Sudoku, but with dice. The maximum score is 8, four rows plus four columns.

The hook is that everyone in the world gets the exact same dice each day. The rolls are generated from a date-based seed, so the puzzle is identical for every player and works fully offline. When you finish, your score lands on a live histogram of how everyone else scored the same puzzle. Was today an easy 8 of 8, or a brutal 4 of 8? You will know, and so will the people you compare with.

Beyond the daily there is a harder weekly 5x5 puzzle that refreshes every Monday, a ladder of fifty hand-curated challenge levels where a perfect score is always reachable, unlimited free play, and community puzzles that players build and pass to a friend with a single link. No ads, no tracking, no analytics SDKs. Sign-in is optional, magic-link only, and exists solely to sync your stats across your phone, tablet, and the web.

05History: about the developers

Yadoku is the first game we ever made, and we made it from two different countries. We are brothers, Blake and Derek, and the distance between us is real, so building something together became our way of staying close. Late-night messages about a dice animation, an argument over a theme color, a new puzzle idea: the game grew out of all of it, and every bit of polish you feel is us trying to do right by each other.

At its heart Yadoku is a daily ritual. You roll dice and place them on a grid to score combos down the rows and columns. Everyone gets the same dice each day, so it is one shared puzzle the whole world is solving at once. There is a weekly challenge, a ladder of levels, and community puzzles you can pass to a friend with a single link.

We built it to be shared. The daily is best when you compare it with the people you care about, the way we compare ours across an ocean. That is what Yadoku is really for: a small, warm thing you do every day with the people you love.
