N1 Casino

A calm, colourful take on classic sudoku. Soft pastel boards, rounded numbers and an unhurried pace — logic puzzles you actually want to sit with.

THE GOAL
Fill every empty cell so that each row, each column and each 3x3 box contains the digits 1 to 9 exactly once. Easy to learn, satisfying to finish.

TEN LEVELS THAT GROW WITH YOU
Ten hand-tuned stages, from a gentle Warm Up to a real Grandmaster test. Each level leaves fewer numbers on the board and tightens the time and mistake budget, so the challenge rises exactly as fast as your confidence does.

TOOLS THAT HELP, NEVER NAG
Tap a cell, then a number, to place it. Switch on Notes to pencil in candidates while you think. Step back with Undo, clear a slip with Erase, and spend a Hint when a cell just won't click. Row, column and box highlighting keeps your eyes at rest.

MISTAKES MATTER
A wrong number counts as a mistake, and each level allows only a few before the round ends — so there is a reason to slow down and read the board instead of guessing.

STARS, COINS AND A LITTLE SHOP
Finish with no mistakes and under the target time to earn three stars and more coins. Save your coins in the shop for hint packs, and claim a small free gift every day. Everything is earned in-game — no pay-to-win, no real-money purchases.

MADE CALM
No clutter, no timers pushing you, no noise. N1 Casino is built to be the quiet five minutes in your day — on the bus, in a queue, or winding down at night.

Pick a level, take a breath, and fill the grid.
