Tournament rule variants

The two tournament rulesets differ in exactly one thing: what happens when a challenge fails. Everything else (bingo bonus, end-of-game adjustment, strict words) is the same.

The three challenge models

scrabbleTracker supports three penalty types. The active ruleset controls which is in play for a given game.

Points penalty — International Tournament

A challenge that fails costs the challenger a fixed point penalty (default: 5). The penalty applies to the challenger; the play stands.

Used by WGPO and most non-NA tournament circuits.

Challenger plays: nothing (just disputes)
Word ruled:       valid
Result:           Challenger loses 5 points; play stands

Turn loss — North American Tournament (“double challenge”)

A challenge that fails costs the challenger their next turn. They skip; the play stands. The harshest deterrent — a frivolous challenge is rare in NA tournament play because of this rule.

Used by NASPA-sanctioned NA tournaments.

Challenger plays: nothing
Word ruled:       valid
Result:           Play stands; challenger skips their next turn

Free — Casual Standard, House Rules default

No penalty for a failed challenge. Anyone can challenge anything, anytime, with nothing to lose. Friendliest setting; great for kids and beginners learning the dictionary.

Challenger plays: nothing
Word ruled:       valid
Result:           Play stands; nothing else happens

What gets recorded either way

Independent of the penalty type, scrabbleTracker writes every challenge to the move log:

• Who challenged
• Which turn was challenged
• The result — stood if the play survived, overturned if the challenge succeeded
• The point delta applied to the challenger or the player

See Challenges for the in-app workflow.

Which ruleset matches your club?

• NASPA-sanctioned tournaments in North America use turn loss (the “double challenge” rule). Pick North American Tournament.
• WGPO and most international tournaments use a 5-point penalty. Pick International Tournament.
• Anything informal — kitchen-table, classroom, club night where nobody wants to crush the new player — use Casual Standard or House Rules with free challenges.

The penalty is fixed at game-start

Like every other rule, the challenge penalty type is snapshotted into the game when it’s created. Editing the ruleset later does not change how this game’s challenges are scored. See House rules for the immutability guarantee.
