TBlock Duel is a free 1v1 block puzzle game. Challenge a friend or play real people online in head-to-head block puzzle duels.

YOU AND YOUR RIVAL GET THE EXACT SAME THREE PIECES. EVERY ROUND. AT THE SAME TIME.

That is the whole idea. No luck of the draw, no blaming the pieces — two players, identical hands, separate boards. Whoever uses them better wins.

Fill a row or column and it bursts. Hit the level's goal first and you take the level; both boards clear and a harder one starts straight away. A duel never really ends — it just gets harder until somebody stops.

PLAY REAL PEOPLE
Host a match and send a friend the code, or open the Online Arena and get matched with a stranger who is waiting right now. Ranked matches have their own ladder for each match length, and your rating follows you. Wi-Fi, mobile data or a hotspot — you do not need to be in the same room, or the same country.

PLAY ALONE
• Climb — an endless solo tower. Clear the goal, the level rises on the spot.
• Daily Challenge — one board a day, the same for everyone, one attempt.
• Play vs AI — a bot that builds against edges, keeps its board flat, and makes believable mistakes on the easier settings.

EVERY LEVEL CHANGES THE RULES
Columns only. Two lines at once or nothing. Big pieces. No bombs. A board that starts half buried. Rush, with the clock cut in half. The rule is on screen before you start, and if a full line does not burst the game tells you which rule stopped it.

FIGHT BACK
Spend banked bursts to throw junk blocks or freeze cells on your rival's board. Block it with a shield. Blow a hole in your own board with a bomb — which also thaws ice. Everything is earned in play or bought with coins you won.

IT LOOKS DIFFERENT EVERY FEW LEVELS
Fifteen colour themes and nine kinds of weather — summer haze, snow, storm and lightning, autumn leaves, fog, aurora, a meteor shower, deep space. Blocks dress for the season and pay a bonus when you clear them.

BUILT TO BE FAIR
Falling behind gets you kinder pieces, an extra turn and bursts worth more, so a comeback is always on. Running out of space costs you points, not the level. A dropped connection never costs you the match — but in ranked, walking away from one does.
