Turn4 vs RobozzleReboot

Turn4 is a twist on the classic 4-in-a-row board game. In Turn4 not only can you drop a playing piece in the column of your choice but you can also rotate the board 90 degrees left or right! This leads to surprising wins where it's more possible to get 5 in a row, 2 different 4-in-a-rows, or even create a tie when both players get a 4-in-a-row. The longer the run, and/or the more simultaneous runs the higher your score! Turn4 has multiple play options. You can play against the computer with an adjustable skill level or against another player on the same device, network play against 1 nearby device via Bluetooth/Wifi, or play through GameCenter where invitations are supported. The color scheme is selectable between a light and dark version of 20 colors.

Robozzle Reboot brings back the classic robot-programming puzzle game to iOS — write tiny programs to guide a robot around a grid, collect every star, and reach the end. No syntax to memorize: every puzzle is solved by dragging instructions into place. HOW IT WORKS Program your robot with a small set of building blocks: move forward, turn left, turn right, paint a tile, and call one of five subroutines (F1–F5). Any instruction can be conditioned on the color of the tile the robot is standing on, so a handful of slots can express surprisingly deep logic. Run your program step-by-step or at full speed, and iterate until every star is collected. CAMPAIGN + COMMUNITY PUZZLES Work through a curated Campaign of puzzles from Robozzle's original creators, sorted by difficulty from your first steps to genuine head-scratchers.
