I’ve made some significant changes to ensure that Sandoku will run on Internet Explorer 9 and Up. All the in-game tutorials have been updated to ensure that they run reasonably well on modern versions of IE. Prior to today’s update the game would freeze up when viewing the in-game tutorials. Day to Night transitions was also freezing up under IE.

Although Sandoku should be playable under IE9 and IE10, performance isn’t that great. The game is still playable but expect a few jitters here and there. This is due to the fact that the game has to run under Canvas2d. The good news under IE11 the game runs smoothly since it supports WebGL.
