Description
A seven-bag Tetris sequence includes each piece exactly once in every bag.
A seven-bag Tetris sequence includes each piece exactly once in every bag.1
Shuffling complete bags gives a different distribution from drawing each piece independently with replacement.
When to use Tetris Piece Sequence Generator
Use this tool to apply the stated tetris piece sequence generator operation with an explicit input and unit basis.
How to use Tetris Piece Sequence Generator and how it works
- Establish the text or game convention described above.
- Enter seed, bagCount and run the tool.
- Read result.pieces using the output meanings below.
- If input is rejected, correct the stated type, range, ordering or alignment issue and rerun; review successful results under the declared convention.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| seed | Nonblank reproducibility string, at most 256 characters; required even with a supplied random source. | string | required; further conditions in the algorithm |
| bagCount | Bag count, on the basis specified in the algorithm. | number | required; finite; integer from 1 to 64; further conditions in the algorithm |
Require integer bag count 1–64. Fisher–Yates shuffle I,J,L,O,S,T,Z for each bag using one advancing source, then concatenate bags. A nonblank seed of at most 256 characters selects the existing seeded generator unless execution context supplies random. One source advances through the request; supplied samples must be finite in [0,1). These draws are not cryptographically secure.
The default source hashes the seed’s UTF-16 units into an integer state and advances a deterministic arithmetic generator for each sample. A supplied execution-context random source takes precedence; it must return finite values in [0,1). The required seed still must be nonblank and at most 256 characters. These draws are reproducible entertainment or sampling, without cryptographic unpredictability.2
sequence = concatenate(shuffle(all seven pieces) per bag) Apply the declared units, ordering and branch conditions.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the declared output fields. | object |
| result.pieces | Flattened seven-bag piece labels in generated order. | array |

}Limitations and assumptions
The output applies the declared operation to the values you supply. Establish the measurement basis, units, coefficients and any caller-selected rules before interpreting it. The tool does not independently collect or verify observations or decide whether a model or reference applies.
Supply explicit required fields with the documented types and dense aligned arrays. Unknown fields, wrong types and nonfinite numbers are rejected. Branch-specific constraints are explained above. A successful false boolean, negative signed difference, empty slice or unresolved tie is distinct from an input error. Very large inputs or outputs may be rejected by shared resource limits.
