Master the handheld Electronic Sudoku game from Bits and Pieces. Learn step-by-step strategies, tips, and how to use its features for puzzle-solving success.
Quick answer
To solve an electronic Sudoku puzzle, start by choosing a difficulty level, then use the game's built-in memory and answer-check features to place numbers logically, row by row.
Why an electronic version makes Sudoku easier
Unlike paper puzzles, the handheld Electronic Sudoku from Bits and Pieces automatically checks your answers and stores your progress. Its back-lit LED screen is readable in any light, so you can play day or night without squinting. The three difficulty levels let beginners start with simple grids and gradually work up to harder challenges.
What to keep in mind before you start
The game requires 2 AA batteries (not included) and measures about 2-3/4 inches wide by 4-3/4 inches long, making it truly portable. The sound function can be turned off if you prefer quiet play. Sleep mode preserves battery life when you pause.
A common mistake is forgetting to use the memory function to save a partially solved puzzle. Always save before turning off the device so you don't lose your progress.
Step-by-step guide to solving Electronic Sudoku puzzles
- Choose your difficulty and start a new game: Press the power button to turn on the device. Use the menu to select Easy, Medium, or Hard. A new puzzle grid will appear on the LED screen. If you are new to Sudoku, start with Easy to learn the logic without frustration.
- Enter numbers using the keypad: Use the number buttons (1-9) to fill in a cell. Navigate with the directional arrows. The game will not let you place an illegal number—it will reject moves that violate Sudoku rules (no repeats in a row, column, or 3x3 block). If a number won't enter, check that cell's row, column, or block for a duplicate.
- Use the automatic answer check: After filling several cells, press the Check button. The game will highlight any incorrect entries. Correct them immediately to avoid building on a wrong assumption. A common mistake is ignoring the check until the end. Early corrections save time.
- Save your progress with the memory function: When you need to pause, press the Memory button. The current puzzle state is saved. When you turn the device back on, you can resume exactly where you left off. Always save before the device goes into sleep mode automatically—your work is not saved otherwise.
- Solve the puzzle using logic, not guessing: Work through each row and column systematically. Look for cells that can only hold one possible number. Use the process of elimination. The game's automatic answer correction will confirm your final solution. If you get stuck, try the Medium or Hard levels later—they require more advanced strategies like hidden pairs or X-Wing.
