Speed Lock -  a combination lock game

For the Juniper Dev 2026 Game jam!

Made by me and my kids!

A masked bomber has hidden bombs inside the school's lockers, and every locker is sealed with a combination lock. You are Agent Smith: crack each lock to defuse the bombs. Spin the dial, line up the pins on the secret numbers, and unlock the lock!

RUNNING

Just run sspin.exe.

Requires Windows with a Vulkan-capable GPU (any modern graphics driver includes the Vulkan runtime).

Requires a mouse to play.

HOW TO PLAY  (mouse only)

* Click and drag the big dial to spin it. The number under the red pointer at the top is the current reading.

* The TARGET (top-left) shows the 3 numbers of the combination. Line up each pin onto its target number.

* Like a real combination lock, you set the pins by turning ONE WAY, then the OTHER:

     - Turn CLOCKWISE to the first number.

     - Turn COUNTER-CLOCKWISE to the second number.

     - Turn CLOCKWISE to the third number.

  (Each deeper pin needs about one extra full turn to be picked up.)

* Listen for the CLUNK and watch the pointer FLASH GREEN each time a pin lines up on its number. On harder locks the pins are hidden, so this sound/flash is how you find them.

* When all the pins are set, press UNLOCK.
