Great App, 1 Font Request

Have used this app for years because it is so well done. One thing that I believe would help all players and especially the visually impaired would be to place a silhouette or border around the edges of the white numerals. Without that, the white numerals tend to disappear into the background when the player scans the board. One specific result of this condition is that collections of numerals, especially the linear groups of eight numbers, may hide in plain sight for a while instead of being instantly recognizable. Again, this is exacerbated for visually impaired players. Thanks again for this great product.

The best online free sudoku games I've found. Easy to play. Levels are also good - challenging but doable.

Love a Challenge

It never hurts to challenge your brain. I love all the possibilities with this game but only 1 solution.

Excellent for the levels available. An expert or challenge level would be great. Variations like "sum-doku" would be nice too. New game often brings up the game just finished.

if there were shortcut keys to switch from pen to pencil mode would be great to increase my speed.

Pretty basic and simple but has multiple difficulties. As a complete stranger, I definitely recommend it.
