Simdex

The is a new game feature added with the Joyous Japan Update. It is present in the form of two new tabs which can be accessed by clicking the "Active Tasks" button.

Simdex was added to the game due to the fact that over the past nine years a large volume of in game content was generated and locating it was often confusing or difficult. Players would not easily be able to identify what was unlocked in their level and how they could go about completing it. With Simdex, this problem is solved as this is basically an index to the game. It lists all quests, hobbies, buildings etc. and the player can filter it to their own liking. Note that events do not show up in this as they are just temporary in nature.

Progress Tab
This tab will show how much progress you have made in the game in the form of a percentage bar. It is sub divided into several sections
 * 1) Quests: Your progress in the quests - there are 51 in total
 * 2) Professions: Your progress in the professions (police, filmmaker and medical) - there are 3 in total
 * 3) Hobbies: Your progress in completing hobby collection sets - there are 46 in total
 * 4) Monuments: Your progress in building monuments - there are 6 in total
 * 5) House Lots: How many of the available house lots you have built upon - there are 37 in total
 * 6) Careers: Your progress in completing careers - there are 10 in total
 * 7) Buildings: Your progress in building buildings - there are 44 in total

Simdex Tab
This tab is a cool way of showing what features will be unlocked with every new level. Note that some levels do not result in unlocking any features.

Every time you complete one of the items mentioned in the list you will be rewarded with progress points. If you have already unlocked some items before the feature was released you'll still get points for them.
