Built for post-game review
Most games of backgammon turn on two or three moments: the hit you did or did not take, the anchor you left too early, the ace-point checker that never escaped. An analyzer earns its keep by telling you which moments those were. Set up the position from your game — the editor is fast enough to do this from memory or a screenshot — and analyze the roll you faced. You get the full probability picture for each candidate play: single wins, gammons and backgammons for both sides, not just a one-line verdict.
The killer feature for study groups is the shareable link. Every analysis updates the page URL with the exact position and roll, so pasting it into a chat reproduces the whole setup on your friend's screen — no more describing positions point by point. Compare the analyzer's ranking against your table feel, check the equity cost of the play you actually made, and you have the same feedback loop that trains modern experts. For the standard reference on first moves, see the opening move analyses.
Frequently asked questions
Can I analyze positions from a real game I played?
Yes — recreate the position with the tap/drag editor, set who was on roll and the dice, and analyze. The URL then encodes the exact position, so you can bookmark or share every key moment of the game.
What do the gammon percentages mean?
A gammon is winning before your opponent bears off a single checker, worth two points (four for a backgammon). The analyzer shows both sides’ gammon chances because they drive attacking decisions and cube strategy.
