下面详细介绍每种谜题游戏，我会把中文介绍放前面，后面附上原始的英文介绍，以便英文好的朋友来帮助纠正，每种题型介绍后面都附上简单的例题和答案供大家参考。
注：原文发表时间：2012.10月，目前该网站题型远大于36种。

另外在解题过程中，网站提供的4种颜色要熟练应用，默认为黑色标记，但是遇到需要拿不准的情况或者多种选择需要选择一种时，不妨换种颜色继续，如果发现有矛盾时可以一键清除该种颜色。在提交答案时所有颜色都有效，我就经常提交时是五颜六色的。
使用鼠标和键盘都可以做题，标黑色或符号时比较简单，大家可摸索掌握，下面主要说一下数字题的输入方法：
鼠标做题：鼠标点击一次是1，然后每点击一次+1，到达最大数字后归零。也可以进入标注模式，点击格子的右下角，然后用鼠标点击位置做标注，再次点击格子的右下角可以退出标注模式，此时剩下的唯一数字可以自动变大。
键盘做题：数字键在格子中输入数字，空格键删除数字，减号键可以输入数字范围，#键可以在正常模式和标注模式间切换，在标注模式下也可以使用数字键进行标注。

01="ABC-Box" (ABC-Box)
ABC盒子：在每个空格内填上指定字母，外周的提示表示该行/列的字母情况，连续相邻的字母记录仅仅一次。问号代表可以是任意一个字母。数字可以代表任一个指定字母，指定字母在图下方会给出。
Write one of the specified letters in each cell of the diagram.The letters by the grid indicate the sequence that the letters appear in that row or column, in the correct order.The same letter appearing consecutively will only be specified once.A question mark or a number in the given sequence indicates an unknown letter; a number indicates thatthe unknown letter will fill that number of consecutive squares.

02="ABCD-Ratsel" (ABCD puzzle)
ABCD:将所给给出的字母选择其一填入空白格中。周围的提示表示每个字母在该行或列出现的次数，每格字母和其周围八格字母都不同。谜题中有对角可重复和不可重复两种情况，题目中会说明，verboten表示不可重复，erlaubt表示可重复。
Write one letter from the given range in every cell, so that no two horizontally or vertically
adjacent cells contain the same letter.The numbers given at the side and top of the grid indicate how many times each letter should appear in the respective row or column.If any of the clue numbers are mising, it is up to you to deduce what value should be there.
This puzzle is sometimes published with an extra constraint - "Diagonal berühren verboten".
In this case, no two cells touching diagonally can contain the same letter.
When this extra condition is NOT in force, it will normally say "Diagonal berühren erlaubt".

05="Buchstabensalat" (Easy as ABC)
空档ABC：在部分空格内填上指定字母A、B、C，使得每行、每列中每个字母出现一次，周围的提示表示这个方向可以看到的第一个字母。指定字母在图下方会给出。
Enter the specified letters into the diagram so that every letter occurs once in every row and every column. The letters at the edge indicate the first visible letter in that row or column when looking from that edge.

06="Dominosuche" (Dominoes)
多米诺：把图分解成每两个格子一块骨牌，下方的骨牌在图中只能出现一次。
Divide the puzzle diagram into the given dominoes. Every domino must be used exactly once.

07="Doppelblock" (Double Block)
双块：将盘面中某些空格涂黑，余下的空格填入给出的数字，使得每行、每列均有两个涂黑的格子以及给出的数字序列1-N各一个。周围的数字表示该行/列两个涂黑格之间的数值之和。）
Shade in some of the cells and place numbers in all the remaining cells. Do this in such a way that exactly two cells are shaded in each row and each column, and each number appears exactly once in each row and each column. The numbers on the outside of the puzzle indicate the sum of the numbers between the two shaded cells in that particular row or column.

08="Doppelstern" (Star Battle)
星战：在一些空格上画上星星，使得每行、每列、每个粗线区域内均有2颗星星，星星两两之间不可横向、纵向或斜向相邻。
Fill some cells with stars so that two stars appear in every row, column, and bold-outlined area.
Cells with stars cannot touch each other, not even diagonally.

09="Fillomino" (Fillomino)
菲洛米诺：用数字将整个图填满。最终把整个图划分成各个数字区域，所有的区域内数字相同而且占据的格子数和该区域内数字一样。同样数字的区域不可以在水平或垂直方向上相邻。
Divide the diagram into areas and write a number into every cell. All numbers within an area must be the same, and they must indicate the size of the area. Areas that have the same size may not share an edge, but they may touch at a corner.Numbers that are given at the start may belong to the same area, and there may also be areas that are bigger than any given number.This applet does not handle numbers that are greater than 9.

10="Gebietssummen" (Area Sums)
区域和：这可以看成仅有加法的KenKen。将给出的数字填入空格，使得每行、每列数字不重复，每个粗线区域左上角的数字表示区域内所有数字之和，注意：在区域内数字可以重复。）
Enter digits as indicated into the diagram so that every digit occurs exactly once in every row and every column. The little numbers in the outlined areas show the sum of the digits inside the area.Please note: One area may contain the same digit more than once.

11="Hashi/Hashiwokakero" (Hashi/Bridges)
架桥：用桥梁连接各个小岛。所有的小岛最终联接成一体。桥只能以水平或垂直方向架，在每2个小岛之间最多架2座桥。小岛上架桥的数量依照小岛上标识的数字，不可多也不可少。
Connect the islands by building bridges so that each island is accessible from all others.
Bridges can only be built vertically or horizontally, and cannot pass over other bridges or islands.There are at most two bridges between any two islands.The numbers in the islands to indicate how many bridges are connected to this island.For a valid solution, you need to ensure only that the bridges are all in place.

12="Heyawake" (Heyawake)
数间：图中用粗线把大图分割成多个小房间。在图中涂黑部分黑格使得最终没有黑格在水平和垂直方向上相邻，而且所有的白格联通在一起，在水平和垂直方向上没有白格可以连接多于2个房间的长度。如果房间内有数字则代表该房间内最终有几个黑格，有数字的这个格子也可以涂黑。
Blacken some cells in the diagram so that no two black cells have a common edge and all white cellsare connected (i.e. the black cells may not divide the puzzle into two or more parts). No horizontalor vertical sequence of white cells may span more than two outlined areas. Numbers inside outlinedareas indicate the number of black cells in that area. Cells with numbers may be blackened.For a correct solution only black cells are relevant.
