Modes and levels
In brief
The app's New game menu offers 4 tabs: Classic, Timed, Last Chance and Daily. In each one, you choose a level, from Easy to Extreme, or the Random Challenge. The higher the level, the longer the code and the more possible codes there are.
The levels
| Level | Pegs | Colors | Rows | At most one color | Possible codes |
|---|---|---|---|---|---|
| Easy | 3 | 5 | 10 | once | 60 |
| Intermediate | 4 | 6 | 8 | once | 360 |
| Hard | 5 | 7 | 15 | 2 times | 14 070 |
| Extreme | 6 | 7 | 20 | 3 times | 113 610 |
The "At most one color" column gives the maximum number of copies of the same color in the code. The number of possible codes follows from it: it is calculated from the app's engine, then recalculated by a second program.
The Random Challenge
In each game, the app draws a format: 4 to 6 pegs, 5 to 7 colors and 8 to 20 rows. If there are more pegs than colors, the code necessarily repeats colors; otherwise, repetitions are sometimes allowed, up to 3 copies of a color.
Classic
One game at the chosen level, with no time limit: find the code before the last row.
Timed
A series of 5, 10 or 20 games at the chosen level, played back to back. The app measures the time of each game and the total time of the series. There is no time limit: the timer measures, it doesn't interrupt anything.
Last Chance
All rows except the last are already played by the app, with randomly drawn guesses (never the code) and their real clues. Only one guess remains, on a full row: you have to deduce the code from what is already there. See a solved example.
Daily
Every day, a series of 25 games to play in order, from Easy level to Extreme level, mixing Classic and Last Chance. The day's codes are drawn from the device's date.
| Level | Classic | Last Chance |
|---|---|---|
| Easy | 3 | 2 |
| Intermediate | 3 | 3 |
| Hard | 4 | 3 |
| Extreme | 4 | 3 |
The app keeps the last 60 days. A past day can be viewed, but not replayed.
Display and accessibility
The app's settings let you choose the light theme, the dark theme or the device's theme, the palette and style of the pegs, the color and shape of the clues (small pegs or numbers), and the direction in which the guesses stack. The Accessibility switch replaces the pegs with flat discs bearing a number, a letter or a shape, so you can play without telling colors apart.
