The Smarter Way to Play Lottery Online
Forget outdated number draws—GridJack is Dewakoin’s elite online lottery game where you build your grid, unlock combo patterns, and race for live jackpot pools. Built for players who want more than just luck, GridJack rewards the strategic, the observant, and the bold.
How GridJack Works
GridJack isn’t just a lottery game—it’s an interactive, grid-based system where every line, corner, and diagonal holds potential.
- 5×5 Custom Grid Entry
Pick your numbers and position them strategically across the board. Every round triggers a live draw against that grid. - Combo Jackpot Engine
Match rows, corners, or X-patterns for progressive wins. Bigger patterns = higher payouts. - Live Grid Rush Events
Every hour, GridJack enters Rush Mode—payouts are doubled for combo hits and live leaderboards go active. - Persistent Grid Play
Save your favorite grid and re-enter it across multiple rounds. Track your win rate and tweak for better odds.
How to Maximize GridJack Winnings
- Cover Core Patterns
Focus on X-shapes, outer frames, or diagonal paths to unlock combo multipliers. - Join Grid Sync Mode
Team up with other players. If your synced grids align on a win, you share the pot + unlock bonus tokens. - Activate Bonus Balls
Every 10 draws, Dewakoin randomly assigns Bonus Balls that multiply any matched number’s payout. - Track Win Heatmaps
Use Dewakoin’s visual heatmap tracker to monitor which number zones have paid most in the last 100 draws.
