An unfair synonym is most useful when it pins down the kind of wrong. A law that harms one group is unjust or discriminatory, a judge who leans one way is biased, a match where one team had every advantage was one-sided, and a rude comment you did not earn is uncalled for.
Every situation gets a word list of its own, plus a ladder from street talk to legal language, sample swaps, and the antonyms. Sport gets its own short section on fair play words.

Street talk to legal wording
Those five chips begin with slang and finish with legal wording. Rigged is blunt and suggests someone fixed the outcome. Uneven is mild and neutral. One-sided fits debates, deals and games. Unjust carries moral weight and suits essays on history or ethics. Inequitable is the policy and legal choice, often used for pay, access and resources.
A school essay on voting rights reads better with unjust than with unfair, and a social post reads better with rigged than with inequitable.

Fair play words from sport
Sports have their own unfair vocabulary. A foul or cheap shot is dirty or unsporting. A blow that breaks the rules of decent play is below the belt, which also works for insults in daily life. British speakers sometimes say not cricket, an old-fashioned phrase for anything dishonorable.
A match that is far from even is a mismatch or one-sided contest, which does not mean anyone cheated.
Careful: not every bad thing is unfair
Harsh means severe, and a harsh rule can still be fair if it applies to everyone. Wrong covers more ground, including an honest slip with no injustice at all; see wrong synonyms. Illegal means against the law, and plenty of unfair things are legal. Unlucky means chance went against you, with no one to blame.
Antonyms: words for fair treatment
