Jabar turns algebra into a hands-on puzzle. Every equation is a row of tiles split by a divider. Drag a tile across and it flips to its inverse: +3 becomes −3, ×2 becomes ÷2. Keep going until your target letter stands alone. • 10 levels, from x + 4 = 9 up to real formulas, fractions, squares and factorising • Endless random puzzles, each with a par worked out by a solver • Daily Equation: one puzzle a day, the same for every player, with streaks • Algebra Golf: nine holes, fewest moves wins • Hints, undo, and a step log that records your working • From level 5 you choose the operation yourself, and a wrong choice tips the balance The name comes from al-jabr, "restoring", the move at the heart of the game and the origin of the word algebra. For ages 11 and up.
