VIBRA
Vibra is essentially a memory game for two players. It is a competitive game based on static play phases. VIBRA borns with the aim of training memory through touch. Depending on the mnemonic capabilities of the players, the difficulty of playing the game could become extreme in a short amounth of time. Although the competitive game mechanics is rather simple, the two players are advised to practice a certain attitude to collaboration in order to ease the progression of level. If played correctly, VIBRA paradoxically becomes a compromise between competitiveness and collaboration.

Each player puts 4 fingers on 4 keys, 8 in total, respectively inserted in 2 boxes, opposite each other. The hand is therefore hidden from its opponent. Each key includes a switch and a vibration motor. The phases of the game are punctuated thanks to an LCD screen positioned between the two players:

- it starts with a virtual "dice roll" to decree which player will start the game;
- the chosen player must press a sequence of 4 keys of his choice;
- the sequence is then transmitted to the opponent through the vibrations scanned by the
motors placed in the keys;
- the opponent must then repeat the exact sequence;
- if successful, the opponent can press a new sequence, this time with 5 keys;
- in the event of a failure, the opponent can repeat a new sequence, always with 4 keys;
- the game is repeated up to a maximum of 50 keys.
