Standard sudoku rules applies. Fill the grid with numbers from 1 to 9 so each digit occurs exactly once in every row, column and 3x3 box.

Digits on the thermos increase from the bulb. Digits after 9 is smaller than 9. in other words, 9 connects two thermos who only contains 1-8

I forgot this one too. Well, too easy for me. It’s the same structure as before, but not long enough. Guess that every part count greatly reduce the difficulty of thermos. I still like the previous one with fewer givens and clean border. With this one, the givens kind of interrupt the thermos aesthetic. Long section actually works.

This is probably the first time I realize the existence of blank space in the rules. Simply uncertainty can disrupt the whole trick base. Everything has to be rebuilt brick by brick. This really becomes one of my most common feature in later days. But like negative restraint, uncertainty also has a very small usable variant pool. Calculation, no, my hee-hoo brain can’t take it. Outside clues, possible, but clues are fix in the cell outside. I need inside clues that connect cells to reach my goals.
