Frog Loop

The minefield is invisible. No hints, no preview, no luck.
The only way up is to hop, get it wrong, remember, and come back smarter.

THE LOOP THAT TRAINS YOUR MEMORY

Your frog climbs a hidden field from the bottom up. The mines sit in exactly the same places — every attempt, every session, today and a week from now. The field never changes. The safe path never moves. Only you do.

An explosion sends you back to the start, but it takes your ignorance with it: now you know one more cell. Finish in fewer attempts and you earn more points and stars.

MATH WORLDS: MENTAL ARITHMETIC BECOMES A HABIT

Instead of "guess the cell", every row holds a problem — and the correct answer IS the safe cell. Miscount and you blow up.

• Addition and multiplication — add or multiply by the same number each time
• Digit sums — find the number whose digits add up to N
• Division — which number divides by N with nothing left over
• Powers — squares, cubes, triangular numbers
• Famous sequences — Fibonacci, primes, factorials
• Endless constants — the digits of π and φ in order
• Calculations — start at 1, each row its own operation: + − × ÷ x² x³ √ ∛

This is not a side mini-game: the problems come dozens in a row, no calculator, no room for error. Mental math is an ordinary skill and it grows with repetition. After a week of climbing you catch yourself adding up the bill before you have reached for your phone.

ENDLESS CALCULATIONS

You choose which operations stay in and how big the numbers get. The board is new every time: addition only — or everything at once, roots and cubes included. The reward moves honestly with the difficulty.

YOUR OWN LEVELS

Type in anything — a phone number, a date, a PIN, a word — and the game builds a field out of it. Climb it twice and it stays in your head. A handy way to learn what you were going to have to memorise anyway.

SHOP AND FROGS

Clearing levels pays coins. Spend them on new frogs: patterned skins, crowns, wreaths, helmets.
