Lift Logic: A Free Daily Elevator Puzzle

Lift Logic is a free daily planning puzzle. There is one lift, and people on several floors are waiting for it. The number on each person is the floor they want. You decide where the lift goes next. Every floor it travels is one move, and the goal is to bring everyone to their floor in the number of moves shown, which is the fewest possible. Monday is 4 floors and 3 people. On Friday there are 7 floors and 7 people, and the lift holds only 2.

No sign-up and nothing to install. It runs in your browser on a computer or a phone, and your progress is saved on your device.

  • Tap a floor. The lift travels there. People for that floor get out, and the people waiting there get in.
  • Every floor counts. Going from floor 2 to floor 6 is four moves. The counter shows your moves next to the fewest possible.
  • A small lift. From Wednesday to Saturday the lift holds only two people, so someone may have to wait for the next trip.
  • Stuck? The lightbulb shows a good next floor, or takes you back to the last stop from which the plan still works.

How to play Lift Logic

  1. Look at the people. The number is the floor they want, and the arrow shows up or down.
  2. Tap a floor to send the lift there. The lift does not stop on the floors in between.
  3. People get out at their floor by themselves. People who wait get in by themselves, in the order of the line, while there is room.
  4. You win when everyone has arrived in the number of moves shown at the top.

Tips for fewer moves

  • Count the turns, not the stops. Stopping on the way costs nothing. Changing direction is what costs moves.
  • Fetch before you deliver. If two people want the top floor and one of them waits below, go down first and take both up together.
  • Finish at an end. A good plan often ends at the top or at the bottom. Think about who gets out last.
  • Arrive with room. With a lift for two, do not stop at a floor with people waiting when the lift is full. They stay behind, and you have to come back.
  • Watch the line. People get in from the front of the line. If the lift has one free place, the first person in the line takes it.

Saturday plays like a Wednesday and Sunday like a Tuesday. From Tuesday on, always going to the nearest call costs extra moves.
