Equation Detective is a logic puzzle where you infer who bought what, when, and for how much by translating verbal clues into simple equations and inequalities. You fill in a grid of people, items, days, and prices to crack the case.

Riddle Solver presents real-life word problems as short scenarios – purchases, discounts, and totals – that you translate into one or two equations and solve for the unknown. It frames algebra in familiar contexts like shopping or sharing costs.

Code Breaker turns equation solving into a secret-word cipher: you solve each algebraic formula to get a number, map that number to a letter via a scrambled letter map, and then unscramble the letters to reveal a hidden word. It blends numerical solving with code-breaking fun.

Grid Sum gives you a blank 3×3 (or larger) grid of algebraic expressions and target row and column totals; your task is to solve for x and place each expression so that every row and column sums correctly. It combines equation solving with logical placement.

Chain Reaction unfolds as a sequence of linked problems – each answer becomes the key variable (“a,” “b,” “c,” etc.) in the next equation, so you build and solve a mathematical domino effect. With each step you expand, substitute, and simplify until you reach the final challenge.

Variable Vault turns algebraic relationships into a four-dial combination lock you must crack with logic and equations. Each dial (A, B, C, D) is linked by clues – linear equations, sums, or differences – that you solve to reveal the secret code. By translating each verbal hint into a simple formula, you determine the value of each variable and unlock the vault.

Tangle Trap challenges you to expand and simplify tangled algebraic expressions until they collapse into a simple equation. Each puzzle wraps multiple brackets, like terms, and hidden cancellations into one line that you must “untangle” step by step. The goal is to isolate x and solve confidently by applying expansion, combining like terms, and moving everything to one side.
