Cushion Cascade

Grow the cue ball from 2 to 16, collect a cushion stamp, then pocket it in the northwest gold pocket within eight shots. Tap any board cell to aim in its general direction (one of eight compass directions). Fire travels the selected power, from one to three grid steps. An equal numbered ball merges into the cue and stops the shot immediately; an unequal collision loses. Side cushions reflect the shot and award the required stamp. Corners are pockets, not cushions: entering a wrong pocket, or entering the gold pocket before reaching 16 and earning the stamp, loses. Change power freely before firing. The three target balls are 2, 4 and 8. Predict where a banked shot stops, not only which wall it hits. Keyboard: Tab and Enter/Space operate buttons; R restarts.
