Tetris Line Clear Score Table

Apply explicit line-score table, zero-based level+1 multiplier, caller back-to-back Tetris factor and already computed combo points; no hidden guideline edition, T-spin or perfect-clear rule.

Description

A caller-defined Tetris scoring schedule separates line-clear points, level scaling, back-to-back multiplication and combo awards.

A caller-defined Tetris scoring schedule separates line-clear points, level scaling, back-to-back multiplication and combo awards.^[1]

Enter five nonnegative bases for 0–4 lines, integer level 0–1000, positive back-to-back factor, previous-Tetris flag and nonnegative combo award. Apply the factor only to a four-line clear following a Tetris; add the combo last.

When to use Tetris Line Clear Score Table

Use Tetris Line Clear Score Table when you need to evaluate the supplied records under the calculation and evidence rules below. No universal ruleset, T-spin scoring or combo-history reconstruction is inferred.

Prepare the supplied game state, observations and explicit variant settings. Follow the card, board, coordinate and state conventions in the calculation rules.

How to use Tetris Line Clear Score Table and understand its results

Prepare the supplied game state, observations and explicit variant settings. Follow the card, board, coordinate and state conventions in the calculation rules.
Enter clearedLines, currentZeroBasedLevel, callerBaseLineScores, precedingEligibleClearWasTetris, callerBackToBackTetrisMultiplier, callerComboBonusPoints using the field table and calculation rules, then run the tool.
Read unmultipliedLineClearPoints, backToBackMultiplierApplied, totalCallerModelPoints. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
clearedLines	Cleared lines	number	Required
currentZeroBasedLevel	Current zero based level	number	Required
callerBaseLineScores	Caller base line scores	list of number	Required
precedingEligibleClearWasTetris	Preceding eligible clear was tetris	boolean	Required
callerBackToBackTetrisMultiplier	Caller back to back tetris multiplier	number	Required
callerComboBonusPoints	Caller combo bonus points	number	Required

score=base[lines]×(level+1)×eligibleMultiplier+combo

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
unmultipliedLineClearPoints	Unmultiplied line clear points	number
backToBackMultiplierApplied	Back to back multiplier applied	number
totalCallerModelPoints	Total caller model points	number

Limitations and assumptions

No universal ruleset, T-spin scoring or combo-history reconstruction is inferred.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use T-Spin Three-Corner Rule Check: A basic T-spin screen uses the T piece, a last rotation and occupied pivot corners. Mini/full classification needs additional evidence. For a complementary task, use Single-Elim Byes Next Power of Two: A single-elimination bracket can be padded to the next power of two. Byes reduce contested first-round matches, while every elimination requires a loss.
