Obunsha Deru-jun - Rika DS — About this game
Rika DS uses the material of Obunsha's Rika 1000 to build a science study routine. Rather than stopping at a quiz answer, its sequence asks you to organize the important points, check your understanding and work on practical problems. Results displays and weakness-review functions help choose what to revisit. Begin with a familiar subject, read the explanation and complete its check before moving into the practical task. If a result is weak, return to the relevant point instead of jumping straight to another topic. The DS screen presents the current response method, so follow that task's choices and entry area rather than assuming every exercise uses handwriting.
