How to Play Latch Step
Pick a Vault
Choose Easy, Medium, or Hard. The lock plate shows a one-variable equation. Four brass bolts show possible values.
Solve the Steps
Distribute if needed, move constants, then divide. The answer is an integer. Common misses sit on the other bolts.
Slot the Bolt
Drag the matching value onto the latch, or tap the bolt and then the slot. A hit opens the gate and deals the next plate.
Clear Eight Gates
Chain correct answers to grow the multiplier. Three wrong pins end the run. The results card shows score, opens, and misses.
Key Features
Eight Gates Per Run
Each correct value opens one latch. Clear all eight to finish the vault. Misses spend a pin. Three spent pins seal the run.
Brass Bolts, Not a Worksheet
Four answer bolts sit under a lock plate. Drag a bolt onto the latch, or tap it and then the slot. Hits pop points. Wrong bolts fall out of play.
Three Equation Layers
Easy is add-or-subtract then divide. Medium adds parentheses and distributing. Hard puts the variable on both sides.
Score, Streak, and Best
Hits start at 100 and climb with a streak bonus. A labeled score plaque stays up the whole run. Best is saved per difficulty.
Frequently Asked Questions
What kinds of equations appear?
Easy uses forms like 3x + 5 = 17. Medium uses parentheses such as 4(x − 2) = 20 or x + 14 = 4(2x + 7). Hard puts the variable on both sides, such as 5(x + 2) = 3x + 16.
Are the answers always integers?
Yes. Each plate is built from a chosen integer solution, so you can check by substituting back.
How does scoring work?
A first hit is 100 points. Each extra hit in a row adds 50 more. A miss resets the streak and spends one pin.
Can I mute the sounds?
Yes. The speaker sits in the score row, not the top-right corner, and remembers your choice.
