Concept gate (2026-09-23, Grok 4.7)
Read the stack: flat top, open well, next queue, and the first hole after a loss. The 7-bag explains the long piece; it is not the whole article.
- Emotional posture: practical and specific to this reader.
- Opening: not the cloned scene, ratio, promise pattern.
- Concept gate: yes
1. Concentration claim
In Tetris, a flat stack and one open well carry survival. Speed, T-spin videos, and blaming the randomizer are the noise.
2. Hard anchors
- Tetris Guideline random generator — pieces dealt in bags of seven, one of each. Worst gap before the same piece returns is 12. Older games differ. https://tetris.wiki/Random_Generator
2b. Field 80/20 examples
| Approx % claim | Field / context | Source | Where it will sit |
|---|---|---|---|
| Bag of 7. Maximum wait of 12 other pieces. Not "20% of buttons do 80% of survival" | Guideline randomizer | Tetris Wiki, guideline documentation | The game is not hiding the long piece |
| Intro 20% / 80% is the rule applied to habits | Practice | Hedge in prose | Opening |
3. Original observation
Three games where you are not allowed to cover the well.
4. Ignored majority
Restarting the second the stack looks ugly, blaming the randomizer, a T-spin video before you can clear a line on purpose, a skin.
5. Composite policy
No invented damage percent. NES randomizer is not the 7-bag.
6. Only-on-8020 idea
The I-piece is not hidden in guideline games. The well was the hole.
7. Device budget
Template G. One 8020 move. Two misreads. viz: no. Keep image-8.png. Drop the old charts.
