HARD Penny Dell Logic Problems

HARD Penny Dell Logic Problems centers on solving logic puzzles by using clues to narrow down possibilities in a grid. You can work through the deductions, mark exclusions, and use the grid to record what you have established.

Work through clues and deductions

The solving process is based on reasoning rather than guessing: analyze the clues, eliminate possibilities that cannot be true, and use the remaining options to fill in the grid. As deductions develop, Auto-X can automatically enter X marks when you have deduced an answer. This keeps the grid connected to the conclusions you reach.

Review and get help when needed

If you make a mistaken move, multi-level undo lets you reverse more than one step instead of starting over. When you are stuck, the app provides several kinds of assistance: you can erase errors, request logical hints, or view the full solution. These options provide different levels of help, from correcting work to seeing how the puzzle resolves.

Fit the grid to your screen

The app is described as working best on larger screens, and zoom controls let you enlarge or reduce the grid to fit a phone or tablet. This lets you adjust how much of the puzzle is visible while working through its clues.

Puzzle selection

The first ten puzzles are available for free. Additional volumes can be purchased, with thirty unique puzzles in each volume. The description does not specify further rules or a required order for choosing puzzles, so the documented focus is on solving the selected logic problems with the grid, undo, and hint tools.
