Here's a trick to play Tetris, also known as Klotz on a Siemens S1.
Turn the phone on. Enter PIN. Before the telephone has logged in to the your GSM net do the following steps.
1: Choose F 9 (function settings)
2: Choose send own number and push the right button for choose.
3: Push 9
USE 2 as < and 8 as > , rotate the klotz with 5 and drop with 4.
[I have just heard from one of the programmers of the phone that Tetris was in the phone during development, but it was removed before it was produced. Apparently someone has the patent on games in mobile phones and Siemens didn't want to pay the licensing fees. It was either in Menu F-9-9 or it's not there at all.]
