A cell-by-cell take on Thinkrolls-style physics puzzles. The little king rolls one cell left or right, then drops; 🍪 cookies get eaten as you roll into them, 📦 crates pushed into a hole become a bridge (and never come back), 🛸 hover platforms rise with ⬆, and turning a 🪞 mirror so the 🔦 beam hits the 🔮 opens the door. Kids practise cause and effect and irreversible decisions — think before you push. 40 levels from gentle to tricky, all machine-verified, and every gadget in a level is one you cannot finish without. Exact distances for every position are pre-computed: in 🌱 Easy the arrows turn green / orange / grey, and Dino warns “press Undo” at a dead end. Tap Dino for a four-step lesson (he talks!).
Goal: roll the little crowned king to the 🚩 rainbow door.
How to roll: press ⬅ ➡ below and the king rolls one cell that way, then keeps dropping until something holds him up (gravity!). You can also tap the cell to the left or right of the king. On a desktop use the arrow keys; Z is undo.
Four gadgets: 🍪 a cookie in the way gets eaten as you roll into it; 📦 a crate gets pushed one cell and drops too — push it into a hole to make a bridge (once it falls it never comes back); 🛸 hover platform: roll onto it and press ⬆ to rise to the top, press ⬇ or roll sideways to come down; 🪞 mirror: tap to turn it 90° so the 🔦 light beam hits the 🔮, and the 🚪 door opens (and stays open). Crates, cookies and walls block the light.
One move = one arrow press or one mirror tap.
Dino the coach: tap Dino’s avatar by the thumbnail for the tutorial — four steps (cookie → crate bridge → hover platform → mirror and door). Dino stays quiet while you play, so kids think for themselves.
The way home: under the castle, Dino stands on the stone that shows how many moves are left; a good move hops forward, a bad one hops back.
Color hints (🌱 Easy only): the arrows turn green (one closer), orange (one farther), grey (same) or ✕ (blocked); mirrors get a badge too. Exact distances for every position are pre-computed, so the colors never lie.
Difficulty: 🌱 Easy has color hints; 🌿 Normal keeps only the moves-to-door counter; 🌳 Hard keeps only Dino on the stone path (no numbers).
Stuck? Cookies and fallen crates don’t come back, so dead ends exist — Dino’s path will say “Stuck — press Undo”. Press “🖐 Show me” and a little hand points at the arrow to press or the mirror to tap; it also points once after 10 idle seconds.
Levels: 40 levels from gentle to tricky: cookies and crates → hover platforms → mirrors and doors → everything together. All machine-verified, and every gadget in a level is one you cannot finish without. Tap “Level N ▾” to jump to any level — cleared ones get a ⭐.
Settings: difficulty, level, sound and voice are tucked away by default so little fingers can’t mess with them; tap the 🌼 above the game to open them, tap again to close.
For parents: this is a cell-by-cell take on Thinkrolls-style physics puzzles: gravity, crate pushing, light reflection and lifts are all there, but every move is a discrete choice you can reason about. Kids practise cause and effect (do this first, then that happens) and irreversible decisions (a crate pushed into a hole is gone, so think before you push). Suits ages 6 and up.
