Teeter Classic vs Nine

Teeter is the classic game where you control a steel ball by tilting a wooden labyrinth. Game has 160 levels with different kind of difficult. Simple and funny interface.

A free, offline sudoku with one new puzzle a day, the same for every player in the world. Five levels, Easy to Evil, each one graded by the technique it actually demands. Nine is a sudoku you can trust. Every sudoku is graded by the technique it actually demands, not by how many squares are blank. When Nine says Expert, you will need an expert's move, not just a grid with fewer clues. Five levels, from Easy to Evil, each one verified strictly harder than the last: Easy asks for the simplest logic, Evil will not resolve without a real X-Wing. ONE SUDOKU A DAY, THE SAME FOR EVERYONE Every player in the world gets the identical daily sudoku, resetting at midnight UTC. Your time is comparable to anyone else's, so today's ladder means something: see how you rank worldwide, right next to your own personal best for that difficulty. Miss a day and the streak breaks, so keep it going. HINTS THAT TEACH Stuck? A hint fills the next square you could have deduced yourself, and names the technique that proves it: naked single, hidden pair, pointing pair, X-Wing. Most sudoku apps just hand you the number. This one shows you the reasoning, so the next grid gets a little easier on its own. Each hint you take adds a small time penalty to your recorded and ranked time, so speed and honesty both still count.
