77RTEnd is a vertical letter‑linking elimination mobile game that combines falling spelling, horizontal repositioning, and dictionary validation into one cohesive rhythm. Letter blocks continuously fall from the top. You can swipe left or right on a falling letter to adjust its landing position. More crucially, you can swipe between adjacent letters to form valid words from the dictionary, which clears them and scores points. Faster, more threatening interference blocks are mixed in; mistakenly linking them or letting letters pile up past the warning line consumes a chance. When chances run out, the round ends. With three chances, continuously accelerating drops, and the cycle of repositioning, word‑linking, and obstacle avoidance, the game is easy to pick up yet requires constant calculation of positions and word choices, making it perfect for high‑score sprints in short sessions.
