BrainBro vs Gemstone Battle!

BrainBro — a colourful, co-operative twist on the classic logic-grid puzzle. Fill the grid so every colour appears once in each row, column, and box — the classic puzzle you already know, reimagined in colour. Play with beautiful gems, flat colours, a soft glow, or classic numbers if you prefer the traditional look. BrainBro is made for playing together. In two-player mode you and a friend, partner, or family member work the same board as a team — no winners, no timers racing you, just solving side by side. And when you get stuck, BrainBro teaches instead of just telling. Its hints walk you through the reasoning step by step — what to notice, why it holds, and the move it leads to — with the pattern drawn right on the board. Prefer a quick nudge?
