Sudoku and Decena · In development, 2026
Losela
A puzzle app with several games inside. Nothing rushes you in any of them.
What it is
Several games inside a single app.
Losela asks what you feel like playing. Today there are two: the sudoku you already know, with several difficulty levels and a keypad built for your thumb, and Decena, pairs that add up to ten, for when you feel like something else without leaving the app.
They share the house rules and the same sky. And there is room for more.
What you will not find in another sudoku
Every board leaves a mark.
When you finish, Losela draws the order in which you closed the nine blocks. A different composition comes out every time, and the game reads it: this board took the shape of The Cartographer, the next one will be The Spiral or The Tide.
It interprets the board, never you. It does not say you are methodical: it says that this time the grid closed like that.
And the marks add up
The sky of signs.
Every shape that appears for the first time lights a constellation in a sky that is yours. The Loom, The Crown, The Shore, The Methodical, The Tide.
There is no “7 of 13”, no grey slots waiting to be filled, no rarities. Just a sky that fills up while you play, and that you can go back and look at whenever you feel like it.
And this is on purpose
What Losela does not have.
None of this was left out for lack of time. It is out because the game is better without it.
- A clock
- Lives
- A score
- Daily streaks
- Leaderboards

The second game
Decena.
Pairs that add up to ten, or that match each other, on a grid that keeps growing. When you run out of moves, you add a new batch and carry on.
It shares the sudoku’s calm, and the sky too: its games leave marks as well.
Day and night
The same game, in two lights.
Pale paper for the midday commute, and a warm night for playing in bed without being dazzled.
