Review momentum
52/100
faster than 53% of Games apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.

About Doku: Metrodoku & Pokédoku
Northern line, crossed with "Zone 1". One cell, two criteria, one name to find. Angel works. Morden doesn't.
That's Doku. A 3×3 grid, nine cells, and at every intersection an answer that has to satisfy the row AND the column. Same idea as sudoku, except you fill it with metro stations, countries or heroes instead of digits.
▶ FIVE UNIVERSES
Metrodoku: Paris, London, New York. Lines, terminus stations, boroughs, interchanges.
Geodoku: countries, capitals, and now the 101 French departments and the 50 US states. Flags, currencies, languages, state capitals, coastlines, rivers.
Loldoku: League of Legends champions.
Pokédoku: all 1025 species.
Dotadoku: Dota 2 heroes, nicknames included. Type "cm" or "antimage" and search keeps up.
You choose which ones appear on your home screen. Hide the rest, without losing any of your scores.
▶ ONE GRID A DAY
The same one for everyone, with its difficulty announced before you start.
▶ THE ORIGINALITY SCORE
Everyone answers King's Cross. Answer something else. The rarer your answer among today's players, the more it scores. A grid finished in thirty seconds with the nine obvious answers is worth very little.
▶ STREAKS, FRIENDS, LEADERBOARD
Miss a day and the streak goes back to zero. Add friends and compare today's grid cell by cell: you find out fairly quickly who was bluffing about knowing the metro.
▶ FREE PLAY
As many grids as you want, easy to expert, offline included.
▶ WHEN AN ANSWER IS REFUSED
The game doesn't just say no. It shows which criterion isn't met, restates the rule, and displays the real value for your answer. You learn something from every miss.
▶ DOKU+
Zero ads, scoring for your free games, every possible answer and your stats vs. everyone, every past grid, unlimited riddles and a streak protected for two days.
No account needed to play: open the app, start a grid.

About Doku: Metrodoku & Pokédoku
Northern line, crossed with "Zone 1". One cell, two criteria, one name to find. Angel works. Morden doesn't.
That's Doku. A 3×3 grid, nine cells, and at every intersection an answer that has to satisfy the row AND the column. Same idea as sudoku, except you fill it with metro stations, countries or heroes instead of digits. A daily trivia quiz that plays like a puzzle.
▶ FIVE UNIVERSES
Metrodoku: the Paris métro, the London Tube, the New York subway. Lines, terminus stations, boroughs, interchanges, stations sitting across two zones.
Geodoku: countries and capitals, and now the 101 French departments and the 50 US states. Flags, currencies, languages, state capitals, coastlines, rivers, time zones.
Loldoku: League of Legends champions. Classes, regions, species, resource, attack range, release year.
Pokédoku: all 1025 species. Types, generations, evolutions, legendaries, colours.
Dotadoku: Dota 2 heroes. Attributes, roles, complexity, Arcanas, heroes from the Netflix series. Search understands nicknames, so "cm" and "antimage" are enough.
And you choose which ones appear on your home screen. Hide the universes you don't care about, without losing any of your scores.
▶ THE DAILY GRID
One new grid a day per universe, the same one for every player, with its difficulty announced before you start. Easy, medium or hard: you know what you are walking into.
▶ THE ORIGINALITY SCORE
Everyone answers King's Cross. Answer something else. The rarer your answer among today's players, the more it scores. That is where the leaderboard is won, not on speed: a grid filled in thirty seconds with the nine obvious answers is worth very little.
▶ STREAKS AND LEADERBOARD
Miss a day and the streak goes back to zero. Every universe keeps its own. The leaderboard gathers the whole community.
▶ WITH FRIENDS
Add friends and compare today's grid cell by cell. You find out fairly quickly who was bluffing about knowing the metro.
▶ FREE PLAY
As many grids as you want, easy to expert, in every universe, offline included. Handy on the underground, as it happens.
▶ WHEN AN ANSWER IS REFUSED
The game doesn't just say no. It shows which criterion isn't met, restates the rule, and displays the real value for your answer. You learn something from every miss.
▶ DOKU+
No ads, with detailed scoring for your free games. And you support an independent developer.
No account needed to play: open the app, start a grid. The daily trivia sudoku, quiz included, in English and in French.
