Four in a row — the connect four game — is the classic connection game on a 7×6 grid: players take turns dropping a piece into a column, it falls to the lowest free spot, and the first to line up four wins. If the grid fills up first, it's a draw.
Here the grid is a timber mine rig deep in a gem cave: two miner clans drop faceted gems down the shafts — glowing rubies against cool sapphires. Every drop lands with a satisfying knock and a spark, and the winning four flashes like a vein of treasure lighting up chain by chain.
No dice, no luck: both players see the whole rig, and every game is decided by who plans further — a perfect first real strategy game.
How to play
Slide across the columns — a ghost gem shows exactly where your drop will land, and the shaft under your finger glows softly. Tap to drop. A full shaft politely refuses.
A three-step voiced tutorial teaches the drop, the goal of four in a row, and the two big secrets: block a rival's three at once, and build a fork — two threats the rival cannot close together. Three rivals grow in strength: Sparkle plays simply and blocks finished fours, Digger already plans a few moves ahead, and the Mountain King calculates deep and punishes every slip. Against Sparkle the game gently warns you before a drop that would hand the rival a winning four. Or pass the tablet and play a friend on one screen.
What your child learns
Four in a row is a school-club classic for early strategy: the child learns to scan lines in four directions, think one move ahead ('if I drop here — what lands on top?'), spot and block threats, and finally to build forks — the first taste of real combinational thinking. Short games keep the feedback loop tight: plan, drop, see the result in seconds.
The science behind the games
Every Dad4Kids game is built on one simple truth: children want to play, not study — so we turn learning into a game worth replaying. The method draws on peer-reviewed research in game-based learning, motivation, and how memory works.

FAQ
My child is 5 — is it too hard?
No. The rule fits in one sentence — drop a gem, make four in a row — and the voiced tutorial shows it on the real rig. The ghost gem removes all guesswork about where a drop lands, and the first rival plays gently and beatably.
Is there any luck involved?
None at all. Both players always see the whole grid. Every win is earned by planning — which is why this game has been a family classic for decades.
What is a fork?
A fork is two winning threats made with one drop. The rival can only block one — the other wins the game. The tutorial explains it, and learning to build forks is the heart of the game's strategy.
Can two children play together?
Yes — the 'two players, one screen' mode: rubies against sapphires on one tablet, and the game announces whose turn it is.
