The Infernal Mountain
Four kids, a forgotten temple under the mountain: agree the words, face the guardians
An illustrated interactive adventure for practising French agreement from Grade 2 to Grade 7. Four present-day kids discover a forgotten temple under a mountain, full of extraordinary animals. In each paragraph the student links the word that commands to the word to agree with the red rope, then picks the right form. Five fights are won with right answers: three hearts of courage, a mistake costs one, and the outcome decides the endings. Three levels, hints that never show the answer.
Audience : Students from Grade 2 to Grade 7, families and teachersLevel : Grades 2 – 7 (ages 7-13)

What the app does
- Three levels: Little Explorer (Grades 2 – 3 – 4), Explorer of the Galleries (Grades 4 – 5 – 6 – 7), Master of the Depths (Grades 5 – 6 – 7).
- 22 illustrated places, each with 2 or 3 agreements to restore: the rest of the text is flawless.
- The touch red rope: touch the word that commands, stretch the rope to the word to agree, pick the form on the wheel.
- Five fights: four rounds, three hearts of courage; a mistake costs a heart, and with no heart left the round starts again with new hearts. A fight without any mistake earns a star.
- A branching story with two endings; the ending “The Peace of the Mountain” needs the last fight won without a mistake.
- Hints in three steps (a question, the rule, the glowing word) that never give the answer.
- Agreements practised: verb and subject, plural of nouns, adjectives, inverted subject, joined subjects, distant subject, object pronoun in between, past participle with être.
- Lexend or OpenDyslexic font, adjustable text size, read aloud, keyboard and tablet.
How it works
- 1ReadA paragraph of the adventure, with two or three agreements to restore.
- 2LinkTouch the word that commands, stretch the red rope to the word to agree.
- 3AgreePick the right form; the Mentor explains why.
- 4FightIn a fight every right answer pushes the foe back; every mistake costs a heart of courage.
Why it is useful
- Grammar spelling becomes an investigation: you look for who commands the word.
- Fights give a real reason to get it right the first time, without ever punishing: when the hearts run out, the round simply starts again.
- A strict dose (2 to 3 agreements per paragraph) so reading is never discouraging.
- Students choose their own path and want to replay to win every fight without a mistake.
Good to know
- This game uses no artificial intelligence: it uses no credit.
- Progress and settings stay in the device's browser; nothing is sent anywhere.
- For teachers: the student gives a progress code (with their first name if they type it); the teacher area gathers the class's codes, shows the least successful agreements, fights won and hearts run out, and exports a CSV.
- The story is played in the interface language: French (agreement), English (a / an, irregular plurals and pasts, pronouns…) or Indonesian (ber- / me-, di / ke, standard words…), with exercises suited to each language.
- Designed for tablets (finger), it also works with a mouse, a keyboard and on phones; it opens in the browser, with nothing to install.
