Kerege Games
Hand-crafted strategy games,
built for your phone.
A small collection of hand-crafted strategy games for Android — sharp AI, honest mathematics, no accounts, no clutter.
Quantum Tic-Tac-Toe
Play Quantum Tic-Tac-Toe — the mind-bending twist on the 3×3 classic. Each turn you place a pair of quantum marks in two squares at once; entangle them into a loop and the board collapses into solid X's and O's — but your opponent chooses how. Line up three classical marks to win.
- Superposition marks & entanglement on a 3×3 grid
- Cyclic collapse — the opponent decides the outcome
- Minimax AI that plays the endgame, not just the rules
- Classic Notebook & neon Siber-Glow themes
- Campaign, daily challenge & achievements
- Offline, no account, no ads tracking you
Sprouts
Play Sprouts and Brussels Sprouts — the elegant mathematical games invented by John Conway and Michael Paterson — rendered with exact topological fidelity. Draw curves between spots, never cross a line, and starve your opponent of legal moves.
- True topology engine — Brussels lasts exactly 5n−2 moves
- Minimax AI that plays the endgame, not just the rules
- Classic Sprouts & Brussels Sprouts variants
- Two premium themes
- Cream notebook & neon cyber-glow modes
- Offline, no account, no ads tracking you
Dots and Boxes
Connect dots, claim squares — the Dots & Boxes game everyone played as a kid (first described by Édouard Lucas in 1889), wrapped in a warm hand-drawn book look. Master the double-cross, chain control, and the half-hearted sacrifice to outscore a sharp AI.
- Hand-drawn book look on cream paper
- Sharp double-cross AI with chain strategy
- Four grid sizes, from quick to brutal
- Classic & Swedish Rim board variants
- 10-level single-player campaign
- Offline, no account, just play
Ultimate Tic-Tac-Toe
Play the Classic 3×3 you grew up with, then switch to Ultimate — nine mini-boards where every square you mark sends your rival to the matching grid. Claim three boards in a line to win the game. Wrapped in the same warm hand-drawn notebook look, with sharp AI and a fresh daily puzzle.
- Classic 3×3 and deep Ultimate nine-board modes
- Three AI difficulties, from warm-up to sharp
- 10-level single-player campaign
- A fresh daily challenge every day
- Notebook & cyber-glow themes
- Offline, no account, just play
Dandelions
Play Dandelions — the elegant two-player abstract where the Dandelion plants flowers and the Wind scatters their seeds across the meadow. Choose a fresh direction each gust; once all eight winds have blown, every empty patch hands victory to the Wind. Cover the whole field and the Dandelion wins. Pure mathematics, no luck, no draws.
- Asymmetric duel — plant flowers vs. blow the wind
- Eight compass winds, each used exactly once
- Standard 5×5 and sprawling Big Meadow 7×7 boards
- Sharp AI that thinks ahead, never just legal
- Calm sky-meadow look, smooth seed animations
- Offline, no account, no ads tracking you
Quantum Eka Tavla
Play Quantum Eka Tavla — Turkish backgammon powered by real quantum algorithms. The dice live in superposition until you observe them, checkers can be entangled so their fates link, and the teal Eka shield guards your points. Roll with the built-in Hadamard simulator or hand the dice to a real IBM Quantum backend.
- Quantum dice — superposition, observation & collapse
- Three modes: Classic Tavla, Full Quantum, Eka Chaos
- Simulator or live IBM Quantum cloud dice source
- Neon crystal board with strict rigid-body dice physics
- Campaign, daily challenge & achievements
- Offline play — the quantum cloud is optional
Spatial Games
Play Spatial Games — five classic pencil-and-paper strategy games from recreational mathematics in one hand-drawn collection: Bunch of Grapes, Neutron, Order & Chaos, Splatter and 3D Tic-Tac-Toe. Trap the rival fly, push the neutron home, make (or wreck) five in a row, be the last paint standing, and connect four across four layers.
- Five complete games in a single app
- Three AI difficulties plus local pass & play
- 15-level campaign and a fresh daily challenge
- Achievements, coins & unlockable board themes
- Hand-drawn notebook & cyber-glow looks, 14 languages
- Offline, no account, just play
