Game Info:
This game displays a select number of correct solutions and all of the possible candidates. You quick-touch a candidate to choose it, and long-touch it to eliminate it as a possibility. Quick-touch a number at the bottom to highlight that candidate number.
Once loaded, quick-touch “New” to start a new level 1 game, or “Same” if you want to play the game that is displayed. “Same” will also restart the last game played. Quick-touch “Daily” to start the Game-of-the-Day. Use the Undo icon to undo moves.
Loses are only registered after 3 failures. The background color of the undo button turns to yellow after the first loss, next is orange and last red.
You can also choose a different game level from the drop-down, with level 1 being the easiest.
The “Empty” option will display a game with only the candidates showing, and the game will “evolve” to the point where you must choose the correct candidate, or you will lose.
Quick-touch “Help” to see a table that displays the Win-Loss data for all 7 levels recorded by all players of this game.
Note: If you find it difficult to touch-activate items with your finger (like me!), using an inexpensive stylus pen for touch screens will help a lot!
