Fundamental Development

Free learning games · built one at a time

Learning games your kid will ask to play.

Short, warm, and built one at a time by a dad with a kindergartner and a two-year-old at home. Each game works on one real skill, turns mistakes into hints instead of penalties, and comes with no ads, no accounts and no trackers — progress stays in your browser.

Kindergarten

ages 4–6

Sight Word Safari

Read words. Restore Wordland!

Fern the fox needs help: the Jumbler scrambled Wordland, and every bridge fixed and flower woken is powered by a word your child reads. Sounds to letters to words, then phrases and sentences, with the tricky “heart parts” taught out loud.

  • Sight words
  • 90 words · 9 worlds
  • 10–15 min a day
  • Narrated
  • Grown-up corner
Play Phone, tablet or laptop. Add it to the home screen for a full-screen game.

Counting Cove

Count, compare, add.

Pip the otter runs the beach at Bubble Bay, and every shell and pearl needs counting. Quick looks, a number-path race, patterns and hidden pearls, built on the research behind the best-tested preschool math programs. Numbers to 20, more and fewer, and the first steps of adding and taking away, all with things your child can see and tap.

  • Counting to 20
  • Patterns
  • Number paths
  • Adding & taking away
Play Ages 4–6 · hosted by Pip the otter. Six coves, a few minutes each.

Hoot’s Discovery Lab

Look closer. Ask why. Try it.

Hoot the owl turns Rainbow Forest into a lab: sort living things from not-living, watch weather and seasons change, and run little experiments where guessing first is the whole point.

  • Living things
  • Weather & seasons
  • Try-it experiments
Play Ages 4–6 · hosted by Hoot the owl. Five stations, a few minutes each.

Dino Keys

Find the letters. Tap the keys.

Rexi the dinosaur helps little fingers find letters on a real keyboard, one key at a time, then the home row. No speed pressure, big friendly targets, and the letters they already know from Wordland.

  • Letter keys
  • Home row
  • No timer
Play Ages 4–6 · hosted by Rexi the dinosaur. Works with a real keyboard or the one on screen.

Story Castle

Listen. Think. Tell it back.

Luna the unicorn reads short stories at Star Castle, then asks the questions that matter: who, what happened, where, and why. Put the story in order, spot how someone felt, learn a new word, catch a sentence that doesn't make sense, and say what comes next.

  • Who, what, where
  • Story order
  • Feelings & why
  • New words
Play Ages 4–6 · hosted by Luna the unicorn. Six short stories and a fact book, read aloud.

Toddlers

ages 2–3

Pebble Pond

Little numbers, together.

Bo the bunny’s first number game, made to be played on a lap. Give Bo two pebbles, show three on a hand, find the pond with the same, tap the one with more, fit the shapes. Sets of one to three that grow only when a number is solid, huge targets, no reading, and a strip that tells the grown-up what to say.

  • Ages 2–3
  • Play together
  • 1, 2, 3
  • Shapes
Play Hosted by Bo the bunny. Five tiny games, a few minutes each, with a grown-up.

How these games are built

One skill, taught properly

Each game picks one thing — like sight words — and teaches it in the order reading research lays out: sounds to letters to whole words, then real sentences. The word lists are ours and still awaiting a literacy specialist’s review; each game’s grown-up corner says so.

Hints, never penalties

A wrong tap gets a nudge and another go. No timers, no lives, no losing. Kids stay in the game long enough to actually learn.

Private by design

No accounts, no ads, no trackers. Progress lives in your browser, and a grown-up corner shows exactly what was practised. The optional microphone stays off until a grown-up turns it on, and uses your browser’s own speech service, like voice typing.

For grown-ups

These games come from a stay-at-home dad building what his own kids need next, in the order they need it. The kindergarten games come first because that’s what a five-year-old can play today; Pebble Pond is the first for toddlers, and it only works with you on the lap too. Every game is free. If something’s off — a word, a voice, a level that’s too hard — the grown-up corner inside each game tells you what the game is doing and why.
