Dozor

Dozor (Russian: Дозор, Watch) is a Russian codebreaking/geolocation game played at night in an urban environment.

Dozor is an outdoors team game, where players aim to complete mentally and physically challenging tasks as fast as possible.

Teams consist of one or more "squads" - 2-5 field players sharing a car. Depending on rules and team strategy, a separate group of players gathered at common remote location may act as team "headquarters" - its functions range from solving the puzzles to directly coordinating "field" squads (i.e. providing addresses and driving directions). Two main game variations exist: "classic" version, highlighting the team synergy, requires 2-8 squads and at least one person as headquarters staff; "lite" version is centered on every player being in action and is played with one squad, no headquarters.

Game flow consists of several levels or "tasks" (original number, declared in rulebook, is 10 levels, however this may change from game to game depending on local rules and game master creativity). At the beginning of each level, team receives a puzzle of some kind. Solving this puzzle provides players with one or several locations in real world that field squads should drive to. Upon arrival to specified location, squad members look for suitable object (building, statue, tree, manhole - almost anything goes here) marked with a game-specific sign (usually letters/numbers/doodle painted with spray can) - the mini-quest of some kind takes place here. As this quest is being completed, the players gather "codes" - lines of digits and letters (i.e. 123D485R). In order to complete the task and advance to next level, team must send all the codes to game masters. Team that completes all the levels within the least time, wins. To balance the tasks, the time-out rule is implemented: if a team doesn't complete a level within given time (90 minutes; this default value may be changed depending on task complexity) - it advances to next level with a time penalty of 15 minutes (in addition to 90 minutes already spent on level). Global time limit - 8 to 12 hours for all levels - may be also present, depending on local rules. Bonus levels, which can be beaten independently of normal ones, and are rewarded with time deductions, may also be present as a part of game.

Puzzles within levels range in complexity with no real bounds existing. Logical puzzles, number and word plays, mini-games - anything goes here, as long as the answer is direct enough to point to exact location. Most game masters try to unite all puzzles and field tasks under the common theme special for the particular game: in this case the game may have a "legend" (short text/video to set the atmosphere) and "prequel" level (more complex level with relaxed time limit), which are made available several days before the game. Since most of puzzles are complex, hints are given at 30 and 60 minutes into each level - second hint usually spells the exact field task location out.
