Mission Impossible: Bombsquare
Good day, agent

Your mission, should you decide to accept it,
is to rescue people from a square where a bomb is planted.
We are not capable of disarming the bomb.
The bomb will go off. We get a signal from the bomb counting
the number of casualties. This signal is only briefly sent.
This signal will be sent 3 times. After receiving the signal you can check
each spot on the square to find matching positions of the bomb.
You have 3 rounds where people move and determine the position of the bomb.
After round 3 the area on your last spot is evacuated and the bomb goes off.
When the wrong field is selected the not evacuated people are killed.
After 25 casualties you get fired. With less you score the surviving people as score.

As always, should you or any of your IM Force be caught or killed,
the Secretary will disavow any knowledge of your actions.

Good luck!

MAX VERSTAPPEN FORMULA ONE PITSTOP SIMULATOR
MAX VERSTAPPEN FORMULA ONE PITSTOP SIMULATOR

You get the change to be part of the pitstop-team from Max Verstappen.
Max enters the pitlane and the tyres must be changed.

You play all 4 teams that changes the wheels. This is possible
by playing first team, your time is recorded and when the team is ready you
play the second team and the computer replays your result. This goes on for
all 4 teams/wheels.

Your keyboardinput must match what is shown. If you start too early or end
to soon you need to restart that key for the time needed.
You can't start before the car stops and time starts. Pressing a key before
the car stops will cost you time.

You change a wheel by pressing the keys in right order.
Take wheel off, move wheel out, move new wheel in and set wheel on car.
The arrows show you what direction to press.

When all wheels are changed Max drives off. You get the "R?".
You can REPLAY the full recorded pitstop now. And as usual....
a new record is shown on the right.

Controls:
Q : Up
A : Down
O : Left
P : Right

R : Replay

NewLine : (re)start game

Hmmmm Just tried it in Eighty One and it does nothing!? Just parks up with an arrow at the rear left wheel and all keys non responsive, or am I doing something wrong?

EDIT.
I can only assume it's a problem on my pc with Eighty One as it is sluggish at the best of times so I tried SZ-81it now works but I have noticed it needs constant key press to go in any direction not just a normal key-press which I think should be mentioned in the instructions

A most unusual but fascinating addition to the 1k corral! :geek:

A wheel doesn't go off by pressing a key once.
You need to press the key a certain time. Release too soon and timer starts over.
And yes.. according to the instructions the controls are QAOP R and NewLine

From the instructions:
