Optimized for iPhone Duo: Rokku now uses the whole screen, folded and unfolded. Timer, streak and tools move into the side strip next to the clock, so the board gets more room. New: on iPad and the unfolded iPhone Duo in landscape, a side panel shows the hint explanation, your best time, your daily streak and the next achievement. New: the Daily Puzzle opens full screen in landscape. Improved: when no simple rule applies, the hint now explains how to find the digit by ruling out. Fixed: an unfinished Daily Puzzle from the day before no longer shows up the next day.

New: Rokku on iPhone Duo and in landscape. The board adapts to the screen size, also when you fold or unfold. New: Daily review in the calendar with a Done button. Fixed: Two wrong digits can now be swapped directly. Fixed: The hint banner no longer touches the number pad.
