Kalah, also called Kalaha or Mancala, is a game in the mancala family invented in the United States by William Julius Champion, Jr. in 1940. This game is sometimes also called "Kalahari", possibly by false etymology from the Kalahari desert in Namibia.
As the most popular and commercially available variant of mancala in the West, Kalah is also sometimes referred to as Warri or Awari, although those names more properly refer to the game Oware.
For most of its variations, Kalah is a solved game with a first-player win if both players play perfect games. The Pie rule can be used to balance the first-player's advantage.
Mark Rawlings has written a computer program to extensively analyze both the "standard" version of Kalah and the "empty capture" version, which is the primary variant. The analysis was made possible by the creation of the largest endgame databases ever made for Kalah. They include the perfect play result of all 38,902,940,896 positions with 34 or fewer seeds. In 2015, for the first time ever, each of the initial moves for the standard version of Kalah(6,4) and Kalah(6,5) have been quantified: Kalah(6,4) is a proven win by 8 for the first player and Kalah(6,5) is a proven win by 10 for the first player. In addition, Kalah(6,6) with the standard rules has been proven to be at least a win by 4. Further analysis of Kalah(6,6) with the standard rules is ongoing.
For the "empty capture" version, Geoffrey Irving and Jeroen Donkers (2000) proved that Kalah(6,4) is a win by 10 for the first player with perfect play, and Kalah(6,5) is a win by 12 for the first player with perfect play. Anders Carstensen (2011) proved that Kalah(6,6) was a win for the first player. Mark Rawlings (2015) has extended these "empty capture" results by fully quantifying the initial moves for Kalah(6,4), Kalah(6,5), and Kalah(6,6). With searches totaling 106 days and over 55 trillion nodes, he has proven that Kalah(6,6) is a win by 2 for the first player with perfect play. This was a surprising result, given that the "4-seed" and "5-seed" variations are wins by 10 and 12, respectively. Kalah(6,6) is extremely deep and complex when compared to the 4-seed and 5-seed variations, which can now be solved in a fraction of a second and less than a minute, respectively.

Santorini is an abstract strategy board game for 2-4 players designed and released in 2004 by Gordon Hamilton and republished via Kickstarter in 2016 by Roxley Games. Inspired by the architecture of cliffside villages on Santorini Island in Greece, and primarily designed for two players, the game is played on a grid where each turn players build a town by placing building pieces up to three levels high. To win the game, players must move one of their two characters to the third level of the town.
Each turn of play involves moving one of your two pieces around a 5-by-5 grid each turn and then placing a tile adjacent to the moved piece, building up that spot of the board. On subsequent turns, pieces may be moved onto one of these built-up tiles, but only one level up at a time. Pieces may also be moved down any number of levels. Players may also place a special dome tile on top of a three-level building, which prevents a player from moving onto that spot for the remainder of the game.
The primary winning condition is to get one of your pieces onto the third level, though players may also win if their opponent is unable to make a move.
The Roxley Games version of Santorini introduced a god powers variant, which gives each player a unique way to break the rules.
After being directly released and sold by Hamilton in 2004, Roxley Games ran a Kickstarter campaign during March-April 2016, drawing over 7,100 backers and raising over C$700,000, the most successful Kickstarter campaign ever based in Alberta. While the original release used plain white blocks as components, the Roxley version featured an enhanced cartoon-like look to the game, which Hamilton credits for success of the Kickstarter campaign. The game was released in retail outlets in January 2017.
