Crypto Logic

is a substitution cipher in which one letter stands for another.

The top pane is the encrypted quote; the pane below it is your work area.

To start, press Set. A keyboard appears. Select the letter you wish to substitute for.

Press Equals. The keyboard again appears. Select the letter you wish to substitute.

The text in the work area shows the change; the key panel on the right shows your substitutions.

• Cancel cancels the current substitution.
• Undo cancels the last substitution.
• Reset lets you start over again.
• New lets you get a different item.
• Hint2 gives a second hint but costs 500 points.
• Hint3 gives a third hint but costs 250 points.
