Great functionality, no ads!!!!

No ads!! Exactly what I was looking for after the Sudoku.com version wouldn’t let me go more than 2 mins without blaring technicolor ads. This one has all the same functionality (number first selection option, static grid guesses instead of the numbers moving). Only wish is some slight color/design adjustments for better legibility, but it is so beyond preferable to the ad slop or horrible interface from every other version.

Судоку

Мне нравится эта игра, она реально на поддержание интеллекта в тонусе, а не тупое нажимание на кнопки. И спасибо, что без рекламы. Вечно она сбивала с толку.
