Trika is a free browser math puzzle game built around a single core mechanic: scan a grid of numbers and find three tiles in a row or column that form a valid equation — like 9−6=3 or 4×5=20. No download, no account, instant play.

Four modes:

Trika — the original. Race the clock, build a streak multiplier, board grows from 3×3 to 5×5 as you find more equations. Operations unlock progressively as you improve.

Trika Blitz — choose 1 or 5 minutes. Fixed 3×3 board, all operations from the start. Wrong guesses cost you 5 seconds. Harder operations score more points.

Trika Precision — a target number appears. Find two adjacent tiles that complete the equation and reach it. Beat the clock.

Trika Survival — numbers fall and stack at the bottom. Tap any three tiles anywhere on the board in equation order to clear them before the board fills up. Speed increases over time.

All four modes have My Runs, Daily, and All-Time leaderboards. The game has built an organic community of players competing daily across Discord and Reddit. Free, no ads, no account needed.
