7 dní a 7 nocí (aka Sedm dní a sedm nocí; English: 7 Days and 7 Nights) is a 1994 Czech adventure game released on MS-DOS through Petr Vochozka's Vochozka Trading brand, and published by Pterodon Software.

[2] The main character, Venca Záhyb, must look after millionaire Jonathan Smiht's 7 daughters and protect them from potential suitors.

However, when he is sitting in a local pub with Fanda Kořen that evening, he bets one lubr that he will get all 7 daughters to the last.

Originally, the developers had planned to follow Tajemství Oslího ostrova (The Secret of the Donkey Island) with an adventure/RPG set at the time of the colonization of Latin America in the vein of the Quest for Glory series.

[1] One popular highlight of the game was an erotic action scene that saw the player press the two mouse buttons alternately to have protagonist Venca Záhyb make the daughters of Mr. Smiht reach climax.
