Real concepts. Played, not taught.

Domino Merge is a dice puzzle your child plays on a small grid. A two-dice piece waits on the side — tap to flip it, then press a spot on the board to drop it. When three matching dice touch along their edges, they pop together into the next bigger number, and if that sets up another match the pops keep going in a happy chain. The skill is spatial planning: where to drop so dice line up, and how to set off a cascade. There's no clock — it's a think-ahead puzzle — but the board fills as you play, so a few careless drops can box you in. Early levels teach the rule with low dice on a small board; later levels raise the target number while the dice you are handed stay low, so your child has to build longer chains. The climb never runs out.

What to watch for: Notice whether your child drops fast or pauses to spot where a third match will land. Planning one drop ahead — setting up a chain instead of a single merge — is the real skill here.

Themed word grids — animals, fruits, colors, school. Tap the start letter, tap the end letter, and the word lights up. Levels grow the grid and the word count, then add diagonals, then reverse spellings, then bigger boards forever. Best level + lifetime score persist; total words found stack up over time.

What to watch for: If your child gets stuck, point at the first letter of a word and let them scan outward. Recognising the start letter is the real reading skill the game trains.

Gobble Monkey is a kid-safe take on the maze-chase classic. Your child swipes to steer a hungry monkey through a maze, gobbling every banana while dodging the ghosts that roam the corridors. Grab the pulsing mango and the whole game flips — the ghosts turn blue and flee, and for a few seconds the monkey is the one doing the chasing. The first levels have no ghosts and no clock so little ones learn to steer; ghosts, then a mango power-up, then more and faster ghosts arrive one at a time. From level 9 the mazes are generated endlessly and grow with your child, so the climb never runs out. There's no harsh 'you lost' — bump a ghost and the monkey just bounces back to the start with a gentle wobble.

What to watch for: Watch whether your child plans an escape route before the ghosts close in, or only reacts once cornered. Reading the threat early — not fast fingers — is the skill this maze is teaching.

Cube Twist is a twisty colour cube your child solves by dragging — pull a row and the whole row of pieces slides together, so a single move visibly changes many pieces at once. That's the whole idea: see what one twist does before you make it. It starts as gently as a cube can — a single face you can fix in one twist — then climbs to a real 2x2, and on to a guided 3x3. A faint arrow always shows the best next twist, so a child is never stuck, only learning. There's no clock — fewer twists earns more stars, rewarding planning over rushing.

What to watch for: Watch whether your child pauses to read what a twist will do before dragging, or twists and checks. Both are real spatial thinking — the goal is noticing that one move changes a whole group.

Three in a Row is single-player tic-tac-toe vs an AI that scales with the level. Easy levels play random moves; medium uses a heuristic (block, take centre, win); hard runs full minimax with alpha-beta pruning — effectively unbeatable. Ten themed levels with star ratings, plus unlockable emoji skins (🐙, 🚀, 🍕). Stars get harder to earn as the AI gets smarter.

What to watch for: If your child wins easy levels every time but stalls at level 5, that's the strategy threshold — the medium AI rewards thinking one move ahead, which is a real cognitive jump.
