Kind of thinking: PlanningYukti #22 was a Tough lift puzzle, the puzzle for Saturday 31 October 2026. Yukti, a daily logic puzzle at playyukti.com, gives everyone the same puzzle each day. Here is the puzzle, and its shortest route with the reason for every step.
The puzzle
Get everything up to your new flat.
The lift carries you and 2 more. Only you can work it.
Everyone and everything is safe while you're with them. Without you, these can't be left together:
- the puppy with the plant, the cake, or the shoes
- the toddler with the cake or the paint
- Once the shoes is upstairs, it stays there.
What is the shortest route?
The shortest route is 7 moves. Each step says why it works.
- 1
Take the puppy and the toddler up.
If you take anything else, the puppy is left with the plant, the cake, the shoes, or the toddler.
- 2
Go down alone.
The puppy and the toddler are safe together.
- 3
Take the plant and the cake up.
Taking the shoes and the paint instead works too.
- 4
Bring the puppy and the toddler down.
The puppy can't be left with the plant, so you bring it down.
- 5
Take the shoes and the paint up.
The puppy and the toddler are safe together.
- 6
Go down alone.
The plant, the cake, the shoes, and the paint are safe together.
- 7
Take the puppy and the toddler up.
Everything is upstairs.
Step 4 is the key step: you bring something down. Sometimes going back is the shortest way forward.
