About Numbers & Letters
Numbers & Letters is a mental arithmetic and vocabulary game, in the spirit of the well-known French TV game show of the same principle, with no affiliation to it.
Two game modes:
* Numbers: 6 numbers are drawn along with a target to reach. Build your calculation step by step, calculator-style, combining the numbers with the 4 basic operations.
* Letters: 10 letters are drawn. Find the longest possible word using these letters before time runs out.
Several ways to play:
* Solo game, with 4 levels of increasing difficulty (Emile, Nestor, Monique, Mathieu), alternating numbers and letters rounds.
* Duo game, for two players on the same phone, with a Duo mode (each keeps their own score) or a Head-to-head mode (only one winner per round).
* Network game, the same duo game but on two separate phones, connected over Wi-Fi or Bluetooth.
* Daily challenge, with a randomly drawn goal each day and trophies for streaks of successful days.
* Streak, timed, words and no-mistake challenges, to progress at your own pace.
* Free training mode, with no time limit and no round limit.
The app keeps track of your statistics and rewards your progress with trophies, offers a light or dark theme, and works entirely offline: no ads, no trackers, no network connection required (except to play a network game).

What's new in 1.133
French dictionary: conjugated verb forms removed. Hard letters (H, J, K, Q, W, X, Y, Z) are drawn less often in French. At the end of a round, the button to continue now replaces the Submit button. Streak and timed challenge trophies for 12 and 15 at Mathieu level moved up to Ruby and Diamond.
