Yoku-Gami is yet another ingenious mathematical game from the legendary Reiner Knizia. With this game, he has taken a simple formula and turned it into a brightly coloured match-3 style game aimed at children.

The object of the game is simple – clear the board of as many tiles as possible. You achieve this by matching up groups of numbered tiles according to this formula: the greatest number in the group must equate to the total of all the other numbers in the group. For example: if you tap tiles with the values of 8, 2, 1 and 5, then your 1, 2 and 5 equal 8. Those tiles are removed and you score points. Your score is calculated on how many numbers are in the group (in this case, 4). When you create groups of five or more numbers, you earn a bonus.

Yoku-Gami has three different game modes: Level, Arcade and Endless and whilst the overall object remains the same, each has a subtle difference.

In Level Mode, the game is played over a number of independent grids (levels). The goal here is to clear as many numbered tiles as possible in the grid. Each game begins with 24 lives, and at the end of each level, the amount of numbers left in the grid is deducted from your total life tally (irrespective of the value of those numbers). Providing you have lives left after this, you will proceed to the next level.

In Arcade Mode, the goal differs, in that you have to clear whole rows or columns of numbers, Tetris-style. Once a row or column is cleared, all the remaining numbers shift down to allow more numbers to enter from above. When you clear two or more rows/columns at the same time, you earn a combo multiplier. When there are no more moves, the game ends.

In Endless Mode, gameplay is similar to Arcade, but the goal is different: clear individual groups of numbers. After each successful turn, the group will disappear from the board and the remaining numbers shift down to allow more numbers to enter from above. Like Arcade mode, when there are no more moves, the game ends.


Whilst Yoku-Gami can be enjoyed by all ages, Reiner Knizia has clearly designed it with children in mind. Kids will love the bright colours and personality of Yoki, the plush teddy/rabbit-like creature who provides hints and shows his appreciation when you achieve bonuses. Unfortunately, this fluffy user interface will likely be a turn-off for most older gamers. Considering the addictive quality and increasing difficulty, it’s surprising that the game was not targeted at a wider demographic. Perhaps if there had been multiple themes, it could have received more exposure.

At any rate, Yoku-Gami is a good quality educational game with no in-app purchases. Appealing visuals, an elegant yet simple user interface, and enough variety to keep your kids happy for hours.


7/10 Yoku-Gami is one of those sweet-spot puzzle games: easy to learn and difficult to master. An ideal purchase for parents wanting to improve their children’s maths skills.
