Easy rules, deep play: take numbers from your row, cut off your opponent’s best moves and beat the AI on ten levels. No ads, no account. gMaxi is a turn-based strategy game played on a grid of numbers. The rules take ten seconds to learn; winning takes a plan. HOW IT WORKS You and your opponent take turns claiming numbers from the grid. You pick from the row of the last taken cell; your opponent picks from its column. Every number you take goes to your score — and every choice decides which numbers your opponent can reach next. The game ends when the active row or column is empty. Highest total wins. PLAY YOUR WAY • Against the gMaxi AI — ten difficulty levels, from a gentle warm-up to a strategist that searches several moves ahead • Two players on one phone — pass it back and forth • Grids from 4×4 to 10×10 • Optional negative numbers, when taking a cell can cost you • Choose who moves first — the opening move is a real advantage FOLLOW YOUR PROGRESS • Match record against the AI: win rate, winning streak, biggest margin, recent results • A detailed summary after every match: who won and by how much, moves, average time per move, duration • Share the result as a card with both names and the final score MADE TO BE COMFORTABLE • 12 languages: English, Ukrainian, German, Polish, Czech, French, Spanish, Portuguese, Italian, Romanian, Bulgarian, Russian • Dark and light appearance • Move sounds and music, each with its own switch • Leave mid-match and pick up exactly where you stopped • Stream mode shows the game name larger for recordings and live streams NO ADS, NO ACCOUNT There are no ads, and you never need to sign up. gMAXI PRO — ONE-TIME PURCHASE The full game is free to play. gMaxi Pro is a single purchase, not a subscription, and adds: • AI levels 9–10 • Large 9×9 and 10×10 grids • Unlimited undo and redo — step back and forward through any match Questions or feedback: support@grabovsky.org
