+
+The *Truth or dare!* game works as follows: a player spins the BBC micro:bit on the table. 
+When the micro:bit stops spinning, the player pointed by the arrow (displayed on screen) must press the button "A" 
+to see if she has to provide a *truth* or a *dare*.
+
+### ~
+
+### Rebuild the game!
+
+The blocks have been shuffled! Put them back together so that...
+* an up arrow is displayed when the micro:bit is powered on.
+* on button `A` is pressed,
+  * randomly display "TRUTH" or "DARE" on the screen
+  * show the up arrow again.
