Unlucky 13 is an endless block puzzle game created by Total Eclipse for Android devices. The game is designed for puzzle lovers of all ages and is free to play. With no timer or countdowns, players can challenge their brains and stay mentally fit while also unwinding. The goal is to place blocks on the board and make lines with tiles of any color. However, if you connect 13 or more tiles of the same color, you lose. The game offers a wide range of tactics to dominate the board, including rotating blocks and using power-ups like Block Refresh to get new blocks. With increasing board progression and difficulty, players can start off with a 6x6 board and try to reach 10x10. Unlucky 13 also offers over 40 unique shapes, most different than ones in other block games. The game features easy-to-pick-up but tough-to-master gameplay, gorgeous graphics, and upbeat music and SFX. Players can unlock more than 10 beautiful, minimal, and soothing themes, discover crazy and tough achievements, participate in leaderboards, and invite friends to join the competition.
